Checking if 17 is a factor: To determine if a number is a factor of 20, we need to check if 20 can be divided by that number without leaving a remainder.Let's start with the number 17.We divide 20 by 17 and see if the remainder is 0.20÷17=1 with a remainder of 3.Since there is a remainder, 17 is not a factor of 20.
Checking if 5 is a factor: Next, we check if 5 is a factor of 20. We divide 20 by 5 and see if the remainder is 0. 20÷5=4 with no remainder. Since there is no remainder, 5 is a factor of 20.
Checking if 9 is a factor: Now, let's check if 9 is a factor of 20. We divide 20 by 9 and see if the remainder is 0. 20÷9=2 with a remainder of 2. Since there is a remainder, 9 is not a factor of 20.
Checking if 7 is a factor: Finally, we check if 7 is a factor of 20. We divide 20 by 7 and see if the remainder is 0. 20÷7=2 with a remainder of 6. Since there is a remainder, 7 is not a factor of 20.
