Greatest Common Divisior

We found the divisors of 124, 132, 39, 670 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 124, 132, 39, 670 is 1.

Therefore, GCD of numbers 124, 132, 39, 670 is 1

Given Input Data is 124, 132, 39, 670

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

Prime Factorization of 124 is 2 x 2 x 31

Prime Factorization of 132 is 2 x 2 x 3 x 11

Prime Factorization of 39 is 3 x 13

Prime Factorization of 670 is 2 x 5 x 67

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(124, 132) = 4092

GCD(124, 132) = ( 124 x 132 ) / 4092

GCD(124, 132) = 16368 / 4092

GCD(124, 132) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 39

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

LCM(4, 39) = 156

GCD(4, 39) = ( 4 x 39 ) / 156

GCD(4, 39) = 156 / 156

GCD(4, 39) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 670

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

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

GCD(1, 670) = 670 / 670

GCD(1, 670) = 1

GCD of 124, 132, 39, 670 is 1
