Given numbers are 120, 921, 994, 351

The list of prime factors of all numbers are

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 921 are 3 x 307

Prime factors of 994 are 2 x 7 x 71

Prime factors of 351 are 3 x 3 x 3 x 13

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

Given numbers are 120, 921, 994, 351

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

Apply this formula for all numbers.

Step1:

LCM(120, 921) = 36840

GCD(120, 921) = ( 120 x 921 ) / 36840

= 120 / 921

= 120

Step2:

LCM(3, 994) = 2982

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

= 3 / 994

= 3

Step3:

LCM(1, 351) = 351

GCD(1, 351) = ( 1 x 351 ) / 351

= 1 / 351

= 1

So, Greatest Common Divisor of 120, 921, 994, 351 is 1
