Given numbers are 320, 861, 751, 121

The list of prime factors of all numbers are

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 861 are 3 x 7 x 41

Prime factors of 751 are 751

Prime factors of 121 are 11 x 11

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

Given numbers are 320, 861, 751, 121

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

Apply this formula for all numbers.

Step1:

LCM(320, 861) = 275520

GCD(320, 861) = ( 320 x 861 ) / 275520

= 320 / 861

= 320

Step2:

LCM(1, 751) = 751

GCD(1, 751) = ( 1 x 751 ) / 751

= 1 / 751

= 1

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 320, 861, 751, 121 is 1
