We found the divisors of 615, 143, 619, 678 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 615, 143, 619, 678 is 1.

Therefore, GCD of numbers 615, 143, 619, 678 is 1

Given Input Data is 615, 143, 619, 678

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

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 143 is 11 x 13

Prime Factorization of 619 is 619

Prime Factorization of 678 is 2 x 3 x 113

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(615, 143) = 87945

GCD(615, 143) = ( 615 x 143 ) / 87945

GCD(615, 143) = 87945 / 87945

GCD(615, 143) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 619

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

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

GCD(1, 619) = 619 / 619

GCD(1, 619) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 678

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

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

GCD(1, 678) = 678 / 678

GCD(1, 678) = 1

GCD of 615, 143, 619, 678 is 1
