Given numbers are 642, 219, 832, 459

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

Apply this formula for all numbers.

Step1:

LCM(642, 219) = 46866

GCD(642, 219) = ( 642 x 219 ) / 46866

= 642 / 219

= 642

Step2:

LCM(3, 832) = 2496

GCD(3, 832) = ( 3 x 832 ) / 2496

= 3 / 832

= 3

Step3:

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

= 1 / 459

= 1

So, Greatest Common Divisor of 642, 219, 832, 459 is 1
