Given numbers are 858, 315, 720, 103

The list of prime factors of all numbers are

Prime factors of 858 are 2 x 3 x 11 x 13

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 103 are 103

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

Given numbers are 858, 315, 720, 103

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

Apply this formula for all numbers.

Step1:

LCM(858, 315) = 90090

GCD(858, 315) = ( 858 x 315 ) / 90090

= 858 / 315

= 858

Step2:

LCM(3, 720) = 720

GCD(3, 720) = ( 3 x 720 ) / 720

= 3 / 720

= 3

Step3:

LCM(3, 103) = 309

GCD(3, 103) = ( 3 x 103 ) / 309

= 3 / 103

= 3

So, Greatest Common Divisor of 858, 315, 720, 103 is 1
