Given numbers are 430, 979, 878, 720

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 979 are 11 x 89

Prime factors of 878 are 2 x 439

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 430, 979, 878, 720

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

Apply this formula for all numbers.

Step1:

LCM(430, 979) = 420970

GCD(430, 979) = ( 430 x 979 ) / 420970

= 430 / 979

= 430

Step2:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 430, 979, 878, 720 is 1
