Given numbers are 641, 815, 454, 977

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

Apply this formula for all numbers.

Step1:

LCM(641, 815) = 522415

GCD(641, 815) = ( 641 x 815 ) / 522415

= 641 / 815

= 641

Step2:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

Step3:

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

= 1 / 977

= 1

So, Greatest Common Divisor of 641, 815, 454, 977 is 1
