question 1 of 3
determine whether each number is a factor of 50.
40 1 3 5 25 10
is a factor
is not a factor

Explanation:

To determine if a number is a factor of 50, we check if 50 is divisible by that number (i.e., the remainder is 0 when 50 is divided by the number).

Step 1: Check for 40

Divide 50 by 40: \( 50 \div 40 = 1 \) with a remainder of 10. So 40 is not a factor.

Step 2: Check for 1

Any number is divisible by 1. \( 50 \div 1 = 50 \) with remainder 0. So 1 is a factor.

Step 3: Check for 3

Divide 50 by 3: \( 50 \div 3 \approx 16.666... \) (remainder 2). So 3 is not a factor.

Step 4: Check for 5

\( 50 \div 5 = 10 \) with remainder 0. So 5 is a factor.

Step 5: Check for 25

\( 50 \div 25 = 2 \) with remainder 0. So 25 is a factor.

Step 6: Check for 10

\( 50 \div 10 = 5 \) with remainder 0. So 10 is a factor.

Answer:

• Is a Factor: 1, 5, 25, 10
• Is Not a Factor: 40, 3
