Given numbers are 88, 78, 31, 72

The list of prime factors of all numbers are

Prime factors of 88 are 2 x 2 x 2 x 11

Prime factors of 78 are 2 x 3 x 13

Prime factors of 31 are 31

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 88, 78, 31, 72

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

Apply this formula for all numbers.

Step1:

LCM(88, 78) = 3432

GCD(88, 78) = ( 88 x 78 ) / 3432

= 88 / 78

= 88

Step2:

LCM(2, 31) = 62

GCD(2, 31) = ( 2 x 31 ) / 62

= 2 / 31

= 2

Step3:

LCM(1, 72) = 72

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

= 1 / 72

= 1

So, Greatest Common Divisor of 88, 78, 31, 72 is 1
