Given numbers are 681, 638, 64

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

Apply this formula for all numbers.

Step1:

LCM(681, 638) = 434478

GCD(681, 638) = ( 681 x 638 ) / 434478

= 681 / 638

= 681

Step2:

LCM(1, 64) = 64

GCD(1, 64) = ( 1 x 64 ) / 64

= 1 / 64

= 1

So, Greatest Common Divisor of 681, 638, 64 is 1
