Given numbers are 128, 612, 316, 978

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

Apply this formula for all numbers.

Step1:

LCM(128, 612) = 19584

GCD(128, 612) = ( 128 x 612 ) / 19584

= 128 / 612

= 128

Step2:

LCM(4, 316) = 316

GCD(4, 316) = ( 4 x 316 ) / 316

= 4 / 316

= 4

Step3:

LCM(4, 978) = 1956

GCD(4, 978) = ( 4 x 978 ) / 1956

= 4 / 978

= 4

So, Greatest Common Divisor of 128, 612, 316, 978 is 2
