We found the divisors of 75, 70, 19 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 75, 70, 19 is 1.

Therefore, GCD of numbers 75, 70, 19 is 1

Given Input Data is 75, 70, 19

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

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 19 is 19

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(75, 70) = 1050

GCD(75, 70) = ( 75 x 70 ) / 1050

GCD(75, 70) = 5250 / 1050

GCD(75, 70) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 19

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

LCM(5, 19) = 95

GCD(5, 19) = ( 5 x 19 ) / 95

GCD(5, 19) = 95 / 95

GCD(5, 19) = 1

GCD of 75, 70, 19 is 1
