Given numbers are 861, 131, 422, 975

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 131 are 131

Prime factors of 422 are 2 x 211

Prime factors of 975 are 3 x 5 x 5 x 13

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

Given numbers are 861, 131, 422, 975

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

Apply this formula for all numbers.

Step1:

LCM(861, 131) = 112791

GCD(861, 131) = ( 861 x 131 ) / 112791

= 861 / 131

= 861

Step2:

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

= 1 / 422

= 1

Step3:

LCM(1, 975) = 975

GCD(1, 975) = ( 1 x 975 ) / 975

= 1 / 975

= 1

So, Greatest Common Divisor of 861, 131, 422, 975 is 1
