Given numbers are 302, 405, 125, 680

The list of prime factors of all numbers are

Prime factors of 302 are 2 x 151

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 125 are 5 x 5 x 5

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 302, 405, 125, 680

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

Apply this formula for all numbers.

Step1:

LCM(302, 405) = 122310

GCD(302, 405) = ( 302 x 405 ) / 122310

= 302 / 405

= 302

Step2:

LCM(1, 125) = 125

GCD(1, 125) = ( 1 x 125 ) / 125

= 1 / 125

= 1

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 302, 405, 125, 680 is 1
