Given numbers are 788, 120, 664, 617

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

Apply this formula for all numbers.

Step1:

LCM(788, 120) = 23640

GCD(788, 120) = ( 788 x 120 ) / 23640

= 788 / 120

= 788

Step2:

LCM(4, 664) = 664

GCD(4, 664) = ( 4 x 664 ) / 664

= 4 / 664

= 4

Step3:

LCM(4, 617) = 2468

GCD(4, 617) = ( 4 x 617 ) / 2468

= 4 / 617

= 4

So, Greatest Common Divisor of 788, 120, 664, 617 is 1
