Given numbers are 315, 720, 851, 873

The list of prime factors of all numbers are

Prime factors of 315 are 3 x 3 x 5 x 7

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

Prime factors of 851 are 23 x 37

Prime factors of 873 are 3 x 3 x 97

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

Given numbers are 315, 720, 851, 873

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

Apply this formula for all numbers.

Step1:

LCM(315, 720) = 5040

GCD(315, 720) = ( 315 x 720 ) / 5040

= 315 / 720

= 315

Step2:

LCM(45, 851) = 38295

GCD(45, 851) = ( 45 x 851 ) / 38295

= 45 / 851

= 45

Step3:

LCM(1, 873) = 873

GCD(1, 873) = ( 1 x 873 ) / 873

= 1 / 873

= 1

So, Greatest Common Divisor of 315, 720, 851, 873 is 1
