Given numbers are 639, 419, 86, 731

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

Apply this formula for all numbers.

Step1:

LCM(639, 419) = 267741

GCD(639, 419) = ( 639 x 419 ) / 267741

= 639 / 419

= 639

Step2:

LCM(1, 86) = 86

GCD(1, 86) = ( 1 x 86 ) / 86

= 1 / 86

= 1

Step3:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

So, Greatest Common Divisor of 639, 419, 86, 731 is 1
