Given numbers are 977, 128, 631, 197

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

Apply this formula for all numbers.

Step1:

LCM(977, 128) = 125056

GCD(977, 128) = ( 977 x 128 ) / 125056

= 977 / 128

= 977

Step2:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

Step3:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

So, Greatest Common Divisor of 977, 128, 631, 197 is 1
