Given numbers are 642, 591, 178, 112

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

Apply this formula for all numbers.

Step1:

LCM(642, 591) = 126474

GCD(642, 591) = ( 642 x 591 ) / 126474

= 642 / 591

= 642

Step2:

LCM(3, 178) = 534

GCD(3, 178) = ( 3 x 178 ) / 534

= 3 / 178

= 3

Step3:

LCM(1, 112) = 112

GCD(1, 112) = ( 1 x 112 ) / 112

= 1 / 112

= 1

So, Greatest Common Divisor of 642, 591, 178, 112 is 1
