Given numbers are 129, 300, 665, 521

The list of prime factors of all numbers are

Prime factors of 129 are 3 x 43

Prime factors of 300 are 2 x 2 x 3 x 5 x 5

Prime factors of 665 are 5 x 7 x 19

Prime factors of 521 are 521

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

Given numbers are 129, 300, 665, 521

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

Apply this formula for all numbers.

Step1:

LCM(129, 300) = 12900

GCD(129, 300) = ( 129 x 300 ) / 12900

= 129 / 300

= 129

Step2:

LCM(3, 665) = 1995

GCD(3, 665) = ( 3 x 665 ) / 1995

= 3 / 665

= 3

Step3:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

So, Greatest Common Divisor of 129, 300, 665, 521 is 1
