Given numbers are 657, 612, 977, 842

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

Apply this formula for all numbers.

Step1:

LCM(657, 612) = 44676

GCD(657, 612) = ( 657 x 612 ) / 44676

= 657 / 612

= 657

Step2:

LCM(9, 977) = 8793

GCD(9, 977) = ( 9 x 977 ) / 8793

= 9 / 977

= 9

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 657, 612, 977, 842 is 1
