Given numbers are 330, 491, 520, 687

The list of prime factors of all numbers are

Prime factors of 330 are 2 x 3 x 5 x 11

Prime factors of 491 are 491

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

Prime factors of 687 are 3 x 229

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

Given numbers are 330, 491, 520, 687

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

Apply this formula for all numbers.

Step1:

LCM(330, 491) = 162030

GCD(330, 491) = ( 330 x 491 ) / 162030

= 330 / 491

= 330

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 330, 491, 520, 687 is 1
