Given numbers are 642, 172, 889, 267

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

Apply this formula for all numbers.

Step1:

LCM(642, 172) = 55212

GCD(642, 172) = ( 642 x 172 ) / 55212

= 642 / 172

= 642

Step2:

LCM(2, 889) = 1778

GCD(2, 889) = ( 2 x 889 ) / 1778

= 2 / 889

= 2

Step3:

LCM(1, 267) = 267

GCD(1, 267) = ( 1 x 267 ) / 267

= 1 / 267

= 1

So, Greatest Common Divisor of 642, 172, 889, 267 is 1
