Given numbers are 656, 978, 225

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

Apply this formula for all numbers.

Step1:

LCM(656, 978) = 320784

GCD(656, 978) = ( 656 x 978 ) / 320784

= 656 / 978

= 656

Step2:

LCM(2, 225) = 450

GCD(2, 225) = ( 2 x 225 ) / 450

= 2 / 225

= 2

So, Greatest Common Divisor of 656, 978, 225 is 1
