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

Apply this formula for all numbers.

Step1:

LCM(789, 635) = 501015

GCD(789, 635) = ( 789 x 635 ) / 501015

= 789 / 635

= 789

Step2:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 789, 635, 656 is 1
