Given numbers are 819, 858, 790, 791

The list of prime factors of all numbers are

Prime factors of 819 are 3 x 3 x 7 x 13

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

Prime factors of 790 are 2 x 5 x 79

Prime factors of 791 are 7 x 113

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

Given numbers are 819, 858, 790, 791

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

Apply this formula for all numbers.

Step1:

LCM(819, 858) = 18018

GCD(819, 858) = ( 819 x 858 ) / 18018

= 819 / 858

= 819

Step2:

LCM(39, 790) = 30810

GCD(39, 790) = ( 39 x 790 ) / 30810

= 39 / 790

= 39

Step3:

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

= 1 / 791

= 1

So, Greatest Common Divisor of 819, 858, 790, 791 is 1
