Question

Whitch statement is true?

Answer 1

Hi There!

• The greatest common factor of 10 and 14 is 5 [FALSE]
• The greatest common factor of 10 and 15 is 5. [TRUE]
• The greatest common factor 13 and 21 is 3. [FALSE]
• The greatest common factor of 14 and 21 is 3. [FALSE]

Step-by-step explanation:

• A factor is a number that a number can be evenly divisible by.
• Example: 5 is a factor of 10, because 10 can be evenly divided by 5.
• Example #2: 3 is not a factor of 13, because 13 is a prime number, which means it has only 2 factors - 13 and 1.
• 3 is not a factor of 14. The factors of 14 are: 1, 2, 7, 14.
• 5 is not a factor of 14 (reason - above)

Hope it helps!

Have an awesome day!
