Given numbers are 972, 145, 847, 126

The list of prime factors of all numbers are

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 145 are 5 x 29

Prime factors of 847 are 7 x 11 x 11

Prime factors of 126 are 2 x 3 x 3 x 7

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

Given numbers are 972, 145, 847, 126

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

Apply this formula for all numbers.

Step1:

LCM(972, 145) = 140940

GCD(972, 145) = ( 972 x 145 ) / 140940

= 972 / 145

= 972

Step2:

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

= 1 / 847

= 1

Step3:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

So, Greatest Common Divisor of 972, 145, 847, 126 is 1
