Find a pair of numbers whose GCF is 25

25 and 50

To find a pair of numbers whose greatest common factor (GCF) is 25, we need to find two numbers that are divisible by 25.

Step 1: Choose any number greater than 25.
Let's choose 50 as our first number.

Step 2: Multiply or divide the first number by 25 to find the second number.
To get a GCF of 25, we can either multiply or divide the first number (50) by 25.

Option 1: Multiply:
50 * 25 = 1250

Option 2: Divide:
50 / 25 = 2

So, a pair of numbers whose GCF is 25 can be (50, 1250) or (50, 2).
