Given numbers are 749, 637, 388, 842

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

Apply this formula for all numbers.

Step1:

LCM(749, 637) = 68159

GCD(749, 637) = ( 749 x 637 ) / 68159

= 749 / 637

= 749

Step2:

LCM(7, 388) = 2716

GCD(7, 388) = ( 7 x 388 ) / 2716

= 7 / 388

= 7

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 749, 637, 388, 842 is 1
