Given numbers are 868, 287, 420, 977

The list of prime factors of all numbers are

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 287 are 7 x 41

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 977 are 977

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

Given numbers are 868, 287, 420, 977

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

Apply this formula for all numbers.

Step1:

LCM(868, 287) = 35588

GCD(868, 287) = ( 868 x 287 ) / 35588

= 868 / 287

= 868

Step2:

LCM(7, 420) = 420

GCD(7, 420) = ( 7 x 420 ) / 420

= 7 / 420

= 7

Step3:

LCM(7, 977) = 6839

GCD(7, 977) = ( 7 x 977 ) / 6839

= 7 / 977

= 7

So, Greatest Common Divisor of 868, 287, 420, 977 is 1
