The square of 28 is divided by the largest number that can exactly divide both 42 and 56. What is the result?

Correct option is D

Given:
Number to be squared: 28
We need to find the largest number that can exactly divide both 42 and 56.
Formula Used:
To find the largest number that can exactly divide two given numbers, we need to find their greatest common divisor (GCD).
Solution:
Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42
Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56
GCD of 42 and 56 =14.
Result = $$\frac{28^2}{14}$$​​

Result = $$\frac{784}{14}$$​​
Result = 56
