Given numbers are 998, 573, 640, 630

The list of prime factors of all numbers are

Prime factors of 998 are 2 x 499

Prime factors of 573 are 3 x 191

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

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 998, 573, 640, 630

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

Apply this formula for all numbers.

Step1:

LCM(998, 573) = 571854

GCD(998, 573) = ( 998 x 573 ) / 571854

= 998 / 573

= 998

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 998, 573, 640, 630 is 1
