Given numbers are 772, 688, 389, 617

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

Apply this formula for all numbers.

Step1:

LCM(772, 688) = 132784

GCD(772, 688) = ( 772 x 688 ) / 132784

= 772 / 688

= 772

Step2:

LCM(4, 389) = 1556

GCD(4, 389) = ( 4 x 389 ) / 1556

= 4 / 389

= 4

Step3:

LCM(1, 617) = 617

GCD(1, 617) = ( 1 x 617 ) / 617

= 1 / 617

= 1

So, Greatest Common Divisor of 772, 688, 389, 617 is 1
