Given numbers are 102, 640, 518, 909

The list of prime factors of all numbers are

Prime factors of 102 are 2 x 3 x 17

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

Prime factors of 518 are 2 x 7 x 37

Prime factors of 909 are 3 x 3 x 101

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

Given numbers are 102, 640, 518, 909

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

Apply this formula for all numbers.

Step1:

LCM(102, 640) = 32640

GCD(102, 640) = ( 102 x 640 ) / 32640

= 102 / 640

= 102

Step2:

LCM(2, 518) = 518

GCD(2, 518) = ( 2 x 518 ) / 518

= 2 / 518

= 2

Step3:

LCM(2, 909) = 1818

GCD(2, 909) = ( 2 x 909 ) / 1818

= 2 / 909

= 2

So, Greatest Common Divisor of 102, 640, 518, 909 is 1
