Greatest Common Divisior

We found the divisors of 46, 78, 55 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 46, 78, 55 is 1.

Therefore, GCD of numbers 46, 78, 55 is 1

Given Input Data is 46, 78, 55

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

Prime Factorization of 46 is 2 x 23

Prime Factorization of 78 is 2 x 3 x 13

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(46, 78) = 1794

GCD(46, 78) = ( 46 x 78 ) / 1794

GCD(46, 78) = 3588 / 1794

GCD(46, 78) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 55

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

LCM(2, 55) = 110

GCD(2, 55) = ( 2 x 55 ) / 110

GCD(2, 55) = 110 / 110

GCD(2, 55) = 1

GCD of 46, 78, 55 is 1
