Given numbers are 639, 762, 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, 762) = 162306

GCD(639, 762) = ( 639 x 762 ) / 162306

= 639 / 762

= 639

Step2:

LCM(3, 731) = 2193

GCD(3, 731) = ( 3 x 731 ) / 2193

= 3 / 731

= 3

So, Greatest Common Divisor of 639, 762, 731 is 1
