The list of prime factors of all numbers are

Prime factors of 977 are 977

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 815 are 5 x 163

Prime factors of 422 are 2 x 211

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

Given numbers are 977, 400, 815, 422

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

Apply this formula for all numbers.

Step1:

LCM(977, 400) = 390800

GCD(977, 400) = ( 977 x 400 ) / 390800

= 977 / 400

= 977

Step2:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

Step3:

LCM(1, 422) = 422

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

= 1 / 422

= 1

So, Greatest Common Divisor of 977, 400, 815, 422 is 1
