Given numbers are 810, 790, 55, 872

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 790 are 2 x 5 x 79

Prime factors of 55 are 5 x 11

Prime factors of 872 are 2 x 2 x 2 x 109

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

Given numbers are 810, 790, 55, 872

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

Apply this formula for all numbers.

Step1:

LCM(810, 790) = 63990

GCD(810, 790) = ( 810 x 790 ) / 63990

= 810 / 790

= 810

Step2:

LCM(10, 55) = 110

GCD(10, 55) = ( 10 x 55 ) / 110

= 10 / 55

= 10

Step3:

LCM(5, 872) = 4360

GCD(5, 872) = ( 5 x 872 ) / 4360

= 5 / 872

= 5

So, Greatest Common Divisor of 810, 790, 55, 872 is 1
