Answer 1

The number that is a factor of 21 but not a multiple of 3 is 5.

Step-by-step explanation:

A factor of a number is a number that divides evenly into that number without leaving a remainder. To find a factor of 21, we need to find a number that divides evenly into 21. Testing the options given, we can see that 7 is a factor of 21 since 21 ÷ 7 = 3 with no remainder. However, 7 is also a multiple of 3 since 3 × 7 = 21. Therefore, the number that is a factor of 21 but not a multiple of 3 is 5.
