Question

write all the factors of 22. use commas to separate them.

Explanation:

Step1: Recall factor definition

A factor of a number \( n \) is an integer that divides \( n \) without leaving a remainder.

Step2: Find factors of 22

Start with 1: \( 22\div1 = 22 \), so 1 and 22 are factors.
Next, 2: \( 22\div2 = 11 \), so 2 and 11 are factors.
Check 3: \( 22\div3\approx7.33 \), not an integer.
Check 4: \( 22\div4 = 5.5 \), not an integer.
Check 5: \( 22\div5 = 4.4 \), not an integer.
Check 6: \( 22\div6\approx3.67 \), not an integer.
Check 7: \( 22\div7\approx3.14 \), not an integer.
Check 8: \( 22\div8 = 2.75 \), not an integer.
Check 9: \( 22\div9\approx2.44 \), not an integer.
Check 10: \( 22\div10 = 2.2 \), not an integer.
Check 11: Already found from \( 22\div2 = 11 \).
Check 22: Already found from \( 22\div1 = 22 \).
So the factors are 1, 2, 11, 22.

Answer:

1, 2, 11, 22
