Given numbers are 605, 403, 672, 991

The list of prime factors of all numbers are

Prime factors of 605 are 5 x 11 x 11

Prime factors of 403 are 13 x 31

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 991 are 991

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

Given numbers are 605, 403, 672, 991

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

Apply this formula for all numbers.

Step1:

LCM(605, 403) = 243815

GCD(605, 403) = ( 605 x 403 ) / 243815

= 605 / 403

= 605

Step2:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

Step3:

LCM(1, 991) = 991

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

= 1 / 991

= 1

So, Greatest Common Divisor of 605, 403, 672, 991 is 1
