Given numbers are 638, 517, 709, 798

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

Apply this formula for all numbers.

Step1:

LCM(638, 517) = 29986

GCD(638, 517) = ( 638 x 517 ) / 29986

= 638 / 517

= 638

Step2:

LCM(11, 709) = 7799

GCD(11, 709) = ( 11 x 709 ) / 7799

= 11 / 709

= 11

Step3:

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

= 1 / 798

= 1

So, Greatest Common Divisor of 638, 517, 709, 798 is 1
