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 147 are 3 x 7 x 7

Prime factors of 994 are 2 x 7 x 71

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Given numbers are 972, 147, 994, 945

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

Apply this formula for all numbers.

Step1:

LCM(972, 147) = 47628

GCD(972, 147) = ( 972 x 147 ) / 47628

= 972 / 147

= 972

Step2:

LCM(3, 994) = 2982

GCD(3, 994) = ( 3 x 994 ) / 2982

= 3 / 994

= 3

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 972, 147, 994, 945 is 1
