We found the divisors of 805, 518, 619, 117 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 805, 518, 619, 117 is 1.

Therefore, GCD of numbers 805, 518, 619, 117 is 1

Given Input Data is 805, 518, 619, 117

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 518 is 2 x 7 x 37

Prime Factorization of 619 is 619

Prime Factorization of 117 is 3 x 3 x 13

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(805, 518) = 59570

GCD(805, 518) = ( 805 x 518 ) / 59570

GCD(805, 518) = 416990 / 59570

GCD(805, 518) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 619

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

LCM(7, 619) = 4333

GCD(7, 619) = ( 7 x 619 ) / 4333

GCD(7, 619) = 4333 / 4333

GCD(7, 619) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 117

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

LCM(1, 117) = 117

GCD(1, 117) = ( 1 x 117 ) / 117

GCD(1, 117) = 117 / 117

GCD(1, 117) = 1

GCD of 805, 518, 619, 117 is 1
