Greatest Common Divisior
We found the divisors of 629, 621, 78, 902 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 629, 621, 78, 902 is 1.
Therefore, GCD of numbers 629, 621, 78, 902 is 1
Given Input Data is 629, 621, 78, 902
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 629 is 17 x 37
Prime Factorization of 621 is 3 x 3 x 3 x 23
Prime Factorization of 78 is 2 x 3 x 13
Prime Factorization of 902 is 2 x 11 x 41
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(629, 621) = 390609
GCD(629, 621) = ( 629 x 621 ) / 390609
GCD(629, 621) = 390609 / 390609
GCD(629, 621) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 78
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 78) = 78
GCD(1, 78) = ( 1 x 78 ) / 78
GCD(1, 78) = 78 / 78
GCD(1, 78) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 902
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 902) = 902
GCD(1, 902) = ( 1 x 902 ) / 902
GCD(1, 902) = 902 / 902
GCD(1, 902) = 1
GCD of 629, 621, 78, 902 is 1
