Given numbers are 744, 644, 129, 457

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

Apply this formula for all numbers.

Step1:

LCM(744, 644) = 119784

GCD(744, 644) = ( 744 x 644 ) / 119784

= 744 / 644

= 744

Step2:

LCM(4, 129) = 516

GCD(4, 129) = ( 4 x 129 ) / 516

= 4 / 129

= 4

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 744, 644, 129, 457 is 1
