Given numbers are 875, 864, 634, 391

The list of prime factors of all numbers are

Prime factors of 875 are 5 x 5 x 5 x 7

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 634 are 2 x 317

Prime factors of 391 are 17 x 23

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

Given numbers are 875, 864, 634, 391

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

Apply this formula for all numbers.

Step1:

LCM(875, 864) = 756000

GCD(875, 864) = ( 875 x 864 ) / 756000

= 875 / 864

= 875

Step2:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 875, 864, 634, 391 is 1
