Given numbers are 640, 686, 650, 829

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 829 are 829

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

Given numbers are 640, 686, 650, 829

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

Apply this formula for all numbers.

Step1:

LCM(640, 686) = 219520

GCD(640, 686) = ( 640 x 686 ) / 219520

= 640 / 686

= 640

Step2:

LCM(2, 650) = 650

GCD(2, 650) = ( 2 x 650 ) / 650

= 2 / 650

= 2

Step3:

LCM(2, 829) = 1658

GCD(2, 829) = ( 2 x 829 ) / 1658

= 2 / 829

= 2

So, Greatest Common Divisor of 640, 686, 650, 829 is 1
