Given numbers are 646, 469, 664

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

Apply this formula for all numbers.

Step1:

LCM(646, 469) = 302974

GCD(646, 469) = ( 646 x 469 ) / 302974

= 646 / 469

= 646

Step2:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 646, 469, 664 is 1
