Given numbers are 814, 516, 638, 649

The list of prime factors of all numbers are

Prime factors of 814 are 2 x 11 x 37

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 638 are 2 x 11 x 29

Prime factors of 649 are 11 x 59

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 814, 516, 638, 649

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

Apply this formula for all numbers.

Step1:

LCM(814, 516) = 210012

GCD(814, 516) = ( 814 x 516 ) / 210012

= 814 / 516

= 814

Step2:

LCM(2, 638) = 638

GCD(2, 638) = ( 2 x 638 ) / 638

= 2 / 638

= 2

Step3:

LCM(2, 649) = 1298

GCD(2, 649) = ( 2 x 649 ) / 1298

= 2 / 649

= 2

So, Greatest Common Divisor of 814, 516, 638, 649 is 1
