Given numbers are 642, 542, 459, 862

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

Apply this formula for all numbers.

Step1:

LCM(642, 542) = 173982

GCD(642, 542) = ( 642 x 542 ) / 173982

= 642 / 542

= 642

Step2:

LCM(2, 459) = 918

GCD(2, 459) = ( 2 x 459 ) / 918

= 2 / 459

= 2

Step3:

LCM(1, 862) = 862

GCD(1, 862) = ( 1 x 862 ) / 862

= 1 / 862

= 1

So, Greatest Common Divisor of 642, 542, 459, 862 is 1
