Given numbers are 809, 570, 142, 770

The list of prime factors of all numbers are

Prime factors of 809 are 809

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 142 are 2 x 71

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 809, 570, 142, 770

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

Apply this formula for all numbers.

Step1:

LCM(809, 570) = 461130

GCD(809, 570) = ( 809 x 570 ) / 461130

= 809 / 570

= 809

Step2:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 809, 570, 142, 770 is 1
