Given numbers are 430, 452, 680, 305

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 452 are 2 x 2 x 113

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

Prime factors of 305 are 5 x 61

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

Given numbers are 430, 452, 680, 305

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

Apply this formula for all numbers.

Step1:

LCM(430, 452) = 97180

GCD(430, 452) = ( 430 x 452 ) / 97180

= 430 / 452

= 430

Step2:

LCM(2, 680) = 680

GCD(2, 680) = ( 2 x 680 ) / 680

= 2 / 680

= 2

Step3:

LCM(2, 305) = 610

GCD(2, 305) = ( 2 x 305 ) / 610

= 2 / 305

= 2

So, Greatest Common Divisor of 430, 452, 680, 305 is 1
