Given numbers are 642, 492, 222, 859

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

Apply this formula for all numbers.

Step1:

LCM(642, 492) = 52644

GCD(642, 492) = ( 642 x 492 ) / 52644

= 642 / 492

= 642

Step2:

LCM(6, 222) = 222

GCD(6, 222) = ( 6 x 222 ) / 222

= 6 / 222

= 6

Step3:

LCM(6, 859) = 5154

GCD(6, 859) = ( 6 x 859 ) / 5154

= 6 / 859

= 6

So, Greatest Common Divisor of 642, 492, 222, 859 is 1
