3 <p>Factors are the numbers that divide another number equally, without leaving any remainder. When you multiply two numbers to find another number, the two which are multiplied are factors. You can think of factors as the building blocks that will help you make numbers.</p>

4 <h2>What are the factors of 217?</h2>

5 <p>Factors are the<a>numbers</a>that help us divide things equally without any leftovers.1,2,79 and 217 are the<a>factors</a><a>of</a>217. The number has both positive and negative<a>integers</a>that divide 217 without leaving any<a>remainder</a>. </p>

6 <h2>How to find the factors of 217?</h2>

7 <p>Factors help us divide numbers equally, making calculations faster and easier. Given below are the methods used to find factors: </p>

8 <h3>Finding Factors Using Multiplication</h3>

9 <p>In this method, we take two numbers and find the<a>product</a>of those two numbers to get the required number.</p>

10 <p>Example: </p>

11 <p>2×79=217</p>

12 <p>1×217=217 </p>

13 <p>This shows that 1, 2,79, and 217 are the factors of 217. </p>

15 <h3>Finding Factors by Division Method</h3>

17 <p>We divide 217 by numbers starting from 1 and see which number gives the remainder of 0.</p>

16 <p>We divide 217 by numbers starting from 1 and see which number gives the remainder of 0.</p>

18 <p>217 ÷1=217</p>

17 <p>217 ÷1=217</p>

19 <p>217 ÷ 2=79</p>

18 <p>217 ÷ 2=79</p>

20 <p>217 ÷ 79=2</p>

19 <p>217 ÷ 79=2</p>

21 <p>217 ÷ 217=1</p>

20 <p>217 ÷ 217=1</p>

22 <p>So the factors are 1,2,79 and 217.</p>

21 <p>So the factors are 1,2,79 and 217.</p>

34 <h3>Problem 1</h3>

35 <p>Is 217 divisible by 3?</p>

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

37 <p>Divisibility Rule for 3: Sum of digits = 2+1+7=102 + 1 + 7 = 102+1+7=10 (not divisible by 3)</p>

38 <p>No, we cannot divide 217 by 3. </p>

39 <h3>Explanation</h3>

40 <p> If the sum of the digits is not divisible by 3, the number is also not. </p>

41 <p>Well explained 👍</p>
