Given numbers are 663, 650, 311, 842

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 311 are 311

Prime factors of 842 are 2 x 421

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

Given numbers are 663, 650, 311, 842

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

Apply this formula for all numbers.

Step1:

LCM(663, 650) = 33150

GCD(663, 650) = ( 663 x 650 ) / 33150

= 663 / 650

= 663

Step2:

LCM(13, 311) = 4043

GCD(13, 311) = ( 13 x 311 ) / 4043

= 13 / 311

= 13

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 663, 650, 311, 842 is 1
