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

Apply this formula for all numbers.

Step1:

LCM(783, 642) = 167562

GCD(783, 642) = ( 783 x 642 ) / 167562

= 783 / 642

= 783

Step2:

LCM(3, 977) = 2931

GCD(3, 977) = ( 3 x 977 ) / 2931

= 3 / 977

= 3

So, Greatest Common Divisor of 783, 642, 977 is 1
