Given numbers are 612, 912, 399, 656

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

Apply this formula for all numbers.

Step1:

LCM(612, 912) = 46512

GCD(612, 912) = ( 612 x 912 ) / 46512

= 612 / 912

= 612

Step2:

LCM(12, 399) = 1596

GCD(12, 399) = ( 12 x 399 ) / 1596

= 12 / 399

= 12

Step3:

LCM(3, 656) = 1968

GCD(3, 656) = ( 3 x 656 ) / 1968

= 3 / 656

= 3

So, Greatest Common Divisor of 612, 912, 399, 656 is 1
