3 <p>The GCF is the largest number that can divide two or more numbers without leaving any remainder. GCF is used to share the items equally, to group or arrange items, and schedule events. In this topic, we will learn about the GCF of 55 and 88.</p>

4 <h2>What is the GCF of 55 and 88?</h2>

5 <p>The<a>greatest common factor</a><a>of</a>55 and 88 is 11.</p>

6 <p>The largest<a>divisor</a>of two or more<a>numbers</a>is called the GCF of the number.</p>

7 <p>If two numbers are co-prime, they have no common factors other than 1, so their GCF is 1.</p>

8 <p>The GCF of two numbers cannot be negative because divisors are always positive.</p>

9 <h2>How to find the GCF of 55 and 88?</h2>

28 <p>Follow these steps:</p>

27 <p>Follow these steps:</p>

29 <p>Step 1: First, divide the larger number by the smaller number Here, divide 88 by 55 88 ÷ 55 = 1 (<a>quotient</a>), The<a>remainder</a>is calculated as 88 - (55×1) = 33 The remainder is 33, not zero, so continue the process.</p>

28 <p>Step 1: First, divide the larger number by the smaller number Here, divide 88 by 55 88 ÷ 55 = 1 (<a>quotient</a>), The<a>remainder</a>is calculated as 88 - (55×1) = 33 The remainder is 33, not zero, so continue the process.</p>

30 <p>Step 2: Now divide the previous divisor (55) by the previous remainder (33) Divide 55 by 33 55 ÷ 33 = 1 (quotient), remainder = 55 - (33×1) = 22. The remainder is 22, not zero, so continue the process.</p>

29 <p>Step 2: Now divide the previous divisor (55) by the previous remainder (33) Divide 55 by 33 55 ÷ 33 = 1 (quotient), remainder = 55 - (33×1) = 22. The remainder is 22, not zero, so continue the process.</p>

31 <p>Step 3: Now divide the previous divisor (33) by the previous remainder (22) Divide 33 by 22 33 ÷ 22 = 1 (quotient), remainder = 33 - (22×1) = 11. The remainder is 11, not zero, so continue the process.</p>

30 <p>Step 3: Now divide the previous divisor (33) by the previous remainder (22) Divide 33 by 22 33 ÷ 22 = 1 (quotient), remainder = 33 - (22×1) = 11. The remainder is 11, not zero, so continue the process.</p>

32 <p>Step 4: Now divide the previous divisor (22) by the previous remainder (11) Divide 22 by 11 22 ÷ 11 = 2 (quotient), remainder = 22 - (11×2) = 0. The remainder is zero; the divisor will become the GCF.</p>

31 <p>Step 4: Now divide the previous divisor (22) by the previous remainder (11) Divide 22 by 11 22 ÷ 11 = 2 (quotient), remainder = 22 - (11×2) = 0. The remainder is zero; the divisor will become the GCF.</p>
