Given numbers are 998, 520, 611, 991

The list of prime factors of all numbers are

Prime factors of 998 are 2 x 499

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 611 are 13 x 47

Prime factors of 991 are 991

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

Given numbers are 998, 520, 611, 991

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

Apply this formula for all numbers.

Step1:

LCM(998, 520) = 259480

GCD(998, 520) = ( 998 x 520 ) / 259480

= 998 / 520

= 998

Step2:

LCM(2, 611) = 1222

GCD(2, 611) = ( 2 x 611 ) / 1222

= 2 / 611

= 2

Step3:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

So, Greatest Common Divisor of 998, 520, 611, 991 is 1
