Question

Which number is a factor of 100?
8
12
15
20

Answer 1

To determine which number is a factor of 100, we can divide 100 by each of the options and check if the result is a whole number.

1. **8**:
\(100 \div 8 = 12.5\) (not a factor)

2. **12**:
\(100 \div 12 \approx 8.33\) (not a factor)

3. **15**:
\(100 \div 15 \approx 6.67\) (not a factor)

4. **20**:
\(100 \div 20 = 5\) (is a factor)

The only number that is a factor of 100 from the given options is **20**.
