Given numbers are 656, 222, 524, 978

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

Apply this formula for all numbers.

Step1:

LCM(656, 222) = 72816

GCD(656, 222) = ( 656 x 222 ) / 72816

= 656 / 222

= 656

Step2:

LCM(2, 524) = 524

GCD(2, 524) = ( 2 x 524 ) / 524

= 2 / 524

= 2

Step3:

LCM(2, 978) = 978

GCD(2, 978) = ( 2 x 978 ) / 978

= 2 / 978

= 2

So, Greatest Common Divisor of 656, 222, 524, 978 is 2
