GCD of numbers is the greatest common divisor

So, the GCD (25, 53, 47, 72) = 1.

Given numbers are 25, 53, 47, 72

The list of prime factors of all numbers are

Prime factors of 25 are 5 x 5

Prime factors of 53 are 53

Prime factors of 47 are 47

Prime factors of 72 are 2 x 2 x 2 x 3 x 3

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 25, 53, 47, 72

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(25, 53) = 1325

GCD(25, 53) = ( 25 x 53 ) / 1325

= 25 / 53

= 25

Step2:

LCM(1, 47) = 47

GCD(1, 47) = ( 1 x 47 ) / 47

= 1 / 47

= 1

Step3:

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

= 1 / 72

= 1

So, Greatest Common Divisor of 25, 53, 47, 72 is 1
