Given numbers are 663, 307, 920, 411

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 307 are 307

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 411 are 3 x 137

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

Given numbers are 663, 307, 920, 411

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

Apply this formula for all numbers.

Step1:

LCM(663, 307) = 203541

GCD(663, 307) = ( 663 x 307 ) / 203541

= 663 / 307

= 663

Step2:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

Step3:

LCM(1, 411) = 411

GCD(1, 411) = ( 1 x 411 ) / 411

= 1 / 411

= 1

So, Greatest Common Divisor of 663, 307, 920, 411 is 1
