Given numbers are 637, 513, 639

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

Apply this formula for all numbers.

Step1:

LCM(637, 513) = 326781

GCD(637, 513) = ( 637 x 513 ) / 326781

= 637 / 513

= 637

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 637, 513, 639 is 1
