Given numbers are 645, 508, 291

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

Apply this formula for all numbers.

Step1:

LCM(645, 508) = 327660

GCD(645, 508) = ( 645 x 508 ) / 327660

= 645 / 508

= 645

Step2:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

So, Greatest Common Divisor of 645, 508, 291 is 1
