Greatest Common Divisior
We found the divisors of 55, 970, 630, 387 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 55, 970, 630, 387 is 1.
Therefore, GCD of numbers 55, 970, 630, 387 is 1
Given Input Data is 55, 970, 630, 387
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 55 is 5 x 11
Prime Factorization of 970 is 2 x 5 x 97
Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7
Prime Factorization of 387 is 3 x 3 x 43
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(55, 970) = 10670
GCD(55, 970) = ( 55 x 970 ) / 10670
GCD(55, 970) = 53350 / 10670
GCD(55, 970) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 630
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 630) = 630
GCD(5, 630) = ( 5 x 630 ) / 630
GCD(5, 630) = 3150 / 630
GCD(5, 630) = 5
Step3:
Here we consider the GCD from the above i.e. 5 as first number and the next as 387
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 387) = 1935
GCD(5, 387) = ( 5 x 387 ) / 1935
GCD(5, 387) = 1935 / 1935
GCD(5, 387) = 1
GCD of 55, 970, 630, 387 is 1
