3 <p>A divisor is a number that divides another number, either exactly or leaving a remainder. In math, division is used to split a number into equal parts, and the divisor plays a key role in this process. In this lesson, we will learn more about divisors.</p>

7 <p>A divisor is a<a>number</a>that divides another number, called the<a>dividend</a>. For example, if A divides B (<a>i</a>.e., B ÷ A), then A is a divisor<a>of</a>B, and A must be a nonzero number. In the<a>division</a>process, dividend, divisor,<a>quotient</a>, and<a>remainder</a>are the four most important terms. The quotient is the result of the division, and the remainder is the part left over when the dividend is not divisible evenly.</p>

8 <p>Take a look at this example: $\frac {30} 5$ </p>

9 <ul><li>Dividend = 30 </li>

10 <li>Divisor = 5 </li>

11 <li>Quotient = 6 </li>

12 <li>Remainder = 0 </li>

13 </ul><h2>Divisor Formula</h2>

14 <p>The divisor<a>formula</a>can be applied in two cases, depending on whether a remainder is present. </p>

15 <ul><li>When the remainder is 0: Divisor = Dividend ÷ Quotient </li>

16 <li>When the remainder is not 0: Divisor = (Dividend - Remainder)Quotient </li>

17 </ul><p>For example,</p>

18 <p>To find the divisor when the dividend is 48, and the quotient is 4.</p>

19 <p>Given, the dividend = 48, and the quotient = 4</p>

20 <p>By using the formula,</p>

21 <p>Divisor = Dividend ÷ Quotient = 48 ÷ 4 = 12</p>

22 <p>So, the divisor is 12.</p>

23 <h2>Difference Between Divisors and Factors</h2>

24 <p>In mathematics, divisors, and<a></a><a>factors</a>both divide a number, but they differ in definition and context. However, they have some differences, which are listed below: </p>

25 <strong>Divisor</strong> <strong>Factors</strong> A divisor is a number that divides another number (dividend). Factors are numbers that divide a number exactly without leaving any remainder. The remainder can be zero or non-zero. A factor divides a number completely, leaving no remainder. For example, $10 ÷ 3 = 3$ with remainder 1.

71 <p>Okay, lets begin</p>

72 <p>84</p>

73 <h3>Explanation</h3>

74 <p>If the remainder is 0, we can use the formula:</p>

75 <p>Divisor = ${Dividend} \over {Quotient}$</p>

76 <p>Divisor = $924 \over 11$ = 84</p>

77 <p>The divisor is 84.</p>

78 <p>Well explained 👍</p>

80 <p>What is the divisor if the dividend is 187, the quotient is 20, and the remainder is 7?</p>

81 <p>Okay, lets begin</p>

82 <p>9</p>

83 <h3>Explanation</h3>

84 <p>If the remainder is a non-zero number, then the formula is: </p>

85 <p>Divisor = $ (Dividend - Remainder) \over Quotient $</p>

86 <p>Now, substitute the values: </p>

87 <p>Divisor = $(187 - 7) \over 20 $</p>

88 <p>= $180 \over 20 $ = 9</p>

89 <p>The divisor is 9.</p>

93 <p>Okay, lets begin</p>

94 <p>15</p>

95 <h3>Explanation</h3>

96 <p>If the remainder is 0, we can use the formula:</p>

97 <p>Divisor = ${Dividend} \over {Quotient}$</p>

98 <p>Divisor = $255 \over 15$ = 15</p>

99 <p>The divisor is 15.</p>

103 <p>Okay, lets begin</p>

104 <p>Yes, 7 is a divisor of 56.</p>

105 <h3>Explanation</h3>

106 <p>To know whether 7 is a divisor of 56, we must divide 56 by 7. $56 \over 7$= 8 </p>

107 <p>The quotient is 8, which is a whole number, and the remainder is 0.</p>

108 <p>Therefore, 7 is a divisor of 56.</p>

109 <p>Well explained 👍</p>

120 <h2>FAQs on Divisor</h2>

121 <h3>1.Define a divisor.</h3>

122 <p>A divisor is a number that divides another number, completely or with a remainder. A number is divisible by its divisors.</p>

123 <p>For example, 28 ÷ 2 = 14. Here, 28 is the dividend and 2 is the divisor.</p>

124 <h3>2.Can a divisor be zero?</h3>

125 <p>No, zero cannot be a divisor. Dividing any number by zero is undefined.</p>

126 <p>For example, 78 ÷ 0 = undefined. If a number is divided by zero, the calculation has no valid meaning.</p>

127 <h3>3.What are the formulas for finding a divisor?</h3>

128 <p>If the remainder is 0, use the formula:</p>

129 <p>Divisor = Dividend ÷ Quotient </p>

130 <p>If the remainder is non-zero, the formula is: </p>

131 <p>Divisor = (Dividend - Remainder) ÷ Quotient</p>

132 <h3>4.Can a divisor always be a whole number?</h3>

133 <p>No, a divisor doesn’t have to be a whole number. It can also be a decimal or a fraction, such as in 200 ÷ 2.5 = 80.</p>
