Given numbers are 325, 664, 639

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

Apply this formula for all numbers.

Step1:

LCM(325, 664) = 215800

GCD(325, 664) = ( 325 x 664 ) / 215800

= 325 / 664

= 325

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 325, 664, 639 is 1
