Given numbers are 656, 215, 494

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

Apply this formula for all numbers.

Step1:

LCM(656, 215) = 141040

GCD(656, 215) = ( 656 x 215 ) / 141040

= 656 / 215

= 656

Step2:

LCM(1, 494) = 494

GCD(1, 494) = ( 1 x 494 ) / 494

= 1 / 494

= 1

So, Greatest Common Divisor of 656, 215, 494 is 1
