Given numbers are 780, 162, 835, 856

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

Prime factors of 835 are 5 x 167

Prime factors of 856 are 2 x 2 x 2 x 107

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

Given numbers are 780, 162, 835, 856

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

Apply this formula for all numbers.

Step1:

LCM(780, 162) = 21060

GCD(780, 162) = ( 780 x 162 ) / 21060

= 780 / 162

= 780

Step2:

LCM(6, 835) = 5010

GCD(6, 835) = ( 6 x 835 ) / 5010

= 6 / 835

= 6

Step3:

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

= 1 / 856

= 1

So, Greatest Common Divisor of 780, 162, 835, 856 is 1
