Given numbers are 977, 645, 790, 773

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

Apply this formula for all numbers.

Step1:

LCM(977, 645) = 630165

GCD(977, 645) = ( 977 x 645 ) / 630165

= 977 / 645

= 977

Step2:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

Step3:

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

= 1 / 773

= 1

So, Greatest Common Divisor of 977, 645, 790, 773 is 1
