Given numbers are 639, 865, 142

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

Apply this formula for all numbers.

Step1:

LCM(639, 865) = 552735

GCD(639, 865) = ( 639 x 865 ) / 552735

= 639 / 865

= 639

Step2:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

So, Greatest Common Divisor of 639, 865, 142 is 1
