Given numbers are 129, 720, 899, 885

The list of prime factors of all numbers are

Prime factors of 129 are 3 x 43

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

Prime factors of 899 are 29 x 31

Prime factors of 885 are 3 x 5 x 59

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

Given numbers are 129, 720, 899, 885

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

Apply this formula for all numbers.

Step1:

LCM(129, 720) = 30960

GCD(129, 720) = ( 129 x 720 ) / 30960

= 129 / 720

= 129

Step2:

LCM(3, 899) = 2697

GCD(3, 899) = ( 3 x 899 ) / 2697

= 3 / 899

= 3

Step3:

LCM(1, 885) = 885

GCD(1, 885) = ( 1 x 885 ) / 885

= 1 / 885

= 1

So, Greatest Common Divisor of 129, 720, 899, 885 is 1
