Given numbers are 128, 736, 790, 442

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

Apply this formula for all numbers.

Step1:

LCM(128, 736) = 2944

GCD(128, 736) = ( 128 x 736 ) / 2944

= 128 / 736

= 128

Step2:

LCM(32, 790) = 12640

GCD(32, 790) = ( 32 x 790 ) / 12640

= 32 / 790

= 32

Step3:

LCM(2, 442) = 442

GCD(2, 442) = ( 2 x 442 ) / 442

= 2 / 442

= 2

So, Greatest Common Divisor of 128, 736, 790, 442 is 2
