Greatest Common Divisior
We found the divisors of 946, 139, 78, 475 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 946, 139, 78, 475 is 1.
Therefore, GCD of numbers 946, 139, 78, 475 is 1
Given Input Data is 946, 139, 78, 475
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 946 is 2 x 11 x 43
Prime Factorization of 139 is 139
Prime Factorization of 78 is 2 x 3 x 13
Prime Factorization of 475 is 5 x 5 x 19
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(946, 139) = 131494
GCD(946, 139) = ( 946 x 139 ) / 131494
GCD(946, 139) = 131494 / 131494
GCD(946, 139) = 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 475
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 475) = 475
GCD(1, 475) = ( 1 x 475 ) / 475
GCD(1, 475) = 475 / 475
GCD(1, 475) = 1
GCD of 946, 139, 78, 475 is 1
