Greatest Common Divisior
We found the divisors of 661, 377, 678, 102 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 661, 377, 678, 102 is 1.
Therefore, GCD of numbers 661, 377, 678, 102 is 1
Given Input Data is 661, 377, 678, 102
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 661 is 661
Prime Factorization of 377 is 13 x 29
Prime Factorization of 678 is 2 x 3 x 113
Prime Factorization of 102 is 2 x 3 x 17
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(661, 377) = 249197
GCD(661, 377) = ( 661 x 377 ) / 249197
GCD(661, 377) = 249197 / 249197
GCD(661, 377) = 1
Step2:
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
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 102
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
GCD(1, 102) = 102 / 102
GCD(1, 102) = 1
GCD of 661, 377, 678, 102 is 1
