We found the divisors of 88, 20, 19 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 88, 20, 19 is 1.

Therefore, GCD of numbers 88, 20, 19 is 1

Given Input Data is 88, 20, 19

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

Prime Factorization of 88 is 2 x 2 x 2 x 11

Prime Factorization of 20 is 2 x 2 x 5

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(88, 20) = 440

GCD(88, 20) = ( 88 x 20 ) / 440

GCD(88, 20) = 1760 / 440

GCD(88, 20) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 19

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

LCM(4, 19) = 76

GCD(4, 19) = ( 4 x 19 ) / 76

GCD(4, 19) = 76 / 76

GCD(4, 19) = 1

GCD of 88, 20, 19 is 1
