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

Apply this formula for all numbers.

Step1:

LCM(978, 756) = 123228

GCD(978, 756) = ( 978 x 756 ) / 123228

= 978 / 756

= 978

Step2:

LCM(6, 956) = 2868

GCD(6, 956) = ( 6 x 956 ) / 2868

= 6 / 956

= 6

Step3:

LCM(2, 782) = 782

GCD(2, 782) = ( 2 x 782 ) / 782

= 2 / 782

= 2

So, Greatest Common Divisor of 978, 756, 956, 782 is 2
