Given numbers are 813, 612, 518, 145

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 518 are 2 x 7 x 37

Prime factors of 145 are 5 x 29

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

Given numbers are 813, 612, 518, 145

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

Apply this formula for all numbers.

Step1:

LCM(813, 612) = 165852

GCD(813, 612) = ( 813 x 612 ) / 165852

= 813 / 612

= 813

Step2:

LCM(3, 518) = 1554

GCD(3, 518) = ( 3 x 518 ) / 1554

= 3 / 518

= 3

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 813, 612, 518, 145 is 1
