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

Apply this formula for all numbers.

Step1:

LCM(978, 246) = 40098

GCD(978, 246) = ( 978 x 246 ) / 40098

= 978 / 246

= 978

Step2:

LCM(6, 656) = 1968

GCD(6, 656) = ( 6 x 656 ) / 1968

= 6 / 656

= 6

Step3:

LCM(2, 880) = 880

GCD(2, 880) = ( 2 x 880 ) / 880

= 2 / 880

= 2

So, Greatest Common Divisor of 978, 246, 656, 880 is 2
