Given numbers are 688, 638, 879, 772

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

Apply this formula for all numbers.

Step1:

LCM(688, 638) = 219472

GCD(688, 638) = ( 688 x 638 ) / 219472

= 688 / 638

= 688

Step2:

LCM(2, 879) = 1758

GCD(2, 879) = ( 2 x 879 ) / 1758

= 2 / 879

= 2

Step3:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 688, 638, 879, 772 is 1
