Given numbers are 640, 990, 481, 519

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 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 481 are 13 x 37

Prime factors of 519 are 3 x 173

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

Given numbers are 640, 990, 481, 519

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

Apply this formula for all numbers.

Step1:

LCM(640, 990) = 63360

GCD(640, 990) = ( 640 x 990 ) / 63360

= 640 / 990

= 640

Step2:

LCM(10, 481) = 4810

GCD(10, 481) = ( 10 x 481 ) / 4810

= 10 / 481

= 10

Step3:

LCM(1, 519) = 519

GCD(1, 519) = ( 1 x 519 ) / 519

= 1 / 519

= 1

So, Greatest Common Divisor of 640, 990, 481, 519 is 1
