Greatest Common Divisior
We found the divisors of 634, 502, 991, 423 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 634, 502, 991, 423 is 1.
Therefore, GCD of numbers 634, 502, 991, 423 is 1
Given Input Data is 634, 502, 991, 423
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 634 is 2 x 317
Prime Factorization of 502 is 2 x 251
Prime Factorization of 991 is 991
Prime Factorization of 423 is 3 x 3 x 47
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(634, 502) = 159134
GCD(634, 502) = ( 634 x 502 ) / 159134
GCD(634, 502) = 318268 / 159134
GCD(634, 502) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 991
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 991) = 1982
GCD(2, 991) = ( 2 x 991 ) / 1982
GCD(2, 991) = 1982 / 1982
GCD(2, 991) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 423
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
GCD(1, 423) = 423 / 423
GCD(1, 423) = 1
GCD of 634, 502, 991, 423 is 1
