Given numbers are 128, 437, 742

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

Apply this formula for all numbers.

Step1:

LCM(128, 437) = 55936

GCD(128, 437) = ( 128 x 437 ) / 55936

= 128 / 437

= 128

Step2:

LCM(1, 742) = 742

GCD(1, 742) = ( 1 x 742 ) / 742

= 1 / 742

= 1

So, Greatest Common Divisor of 128, 437, 742 is 1
