Given numbers are 639, 786, 813, 413

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

Apply this formula for all numbers.

Step1:

LCM(639, 786) = 167418

GCD(639, 786) = ( 639 x 786 ) / 167418

= 639 / 786

= 639

Step2:

LCM(3, 813) = 813

GCD(3, 813) = ( 3 x 813 ) / 813

= 3 / 813

= 3

Step3:

LCM(3, 413) = 1239

GCD(3, 413) = ( 3 x 413 ) / 1239

= 3 / 413

= 3

So, Greatest Common Divisor of 639, 786, 813, 413 is 1
