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

Apply this formula for all numbers.

Step1:

LCM(921, 491) = 452211

GCD(921, 491) = ( 921 x 491 ) / 452211

= 921 / 491

= 921

Step2:

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

= 1 / 77

= 1

So, Greatest Common Divisor of 921, 491, 77 is 1
