We found the divisors of 43, 19, 55 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 43, 19, 55 is 1.

Therefore, GCD of numbers 43, 19, 55 is 1

Given Input Data is 43, 19, 55

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

Prime Factorization of 43 is 43

Prime Factorization of 19 is 19

Prime Factorization of 55 is 5 x 11

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(43, 19) = 817

GCD(43, 19) = ( 43 x 19 ) / 817

GCD(43, 19) = 817 / 817

GCD(43, 19) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 55

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

LCM(1, 55) = 55

GCD(1, 55) = ( 1 x 55 ) / 55

GCD(1, 55) = 55 / 55

GCD(1, 55) = 1

GCD of 43, 19, 55 is 1
