Given numbers are 688, 664, 890

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

Apply this formula for all numbers.

Step1:

LCM(688, 664) = 57104

GCD(688, 664) = ( 688 x 664 ) / 57104

= 688 / 664

= 688

Step2:

LCM(8, 890) = 3560

GCD(8, 890) = ( 8 x 890 ) / 3560

= 8 / 890

= 8

So, Greatest Common Divisor of 688, 664, 890 is 2
