Given numbers are 664, 645, 497

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

Apply this formula for all numbers.

Step1:

LCM(664, 645) = 428280

GCD(664, 645) = ( 664 x 645 ) / 428280

= 664 / 645

= 664

Step2:

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

= 1 / 497

= 1

So, Greatest Common Divisor of 664, 645, 497 is 1
