Question

write all the factors of 49. use commas to separate them.

Explanation:

Step1: Recall factor definition

A factor of a number is an integer that divides the number without leaving a remainder.

Step2: Test divisors for 49

Start with 1: \( 49 \div 1 = 49 \), so 1 and 49 are factors.
Next, 2: \( 49 \div 2 = 24.5 \), not an integer, so 2 is not a factor.
3: \( 49 \div 3 \approx 16.33 \), not an integer.
4: \( 49 \div 4 = 12.25 \), not an integer.
5: \( 49 \div 5 = 9.8 \), not an integer.
6: \( 49 \div 6 \approx 8.17 \), not an integer.
7: \( 49 \div 7 = 7 \), so 7 is a factor.
Numbers greater than 7 (like 8 - 48) will have quotients less than 7, and we already checked up to 7.

Answer:

1, 7, 49
