Greatest Common Divisior
We found the divisors of 278, 946, 31, 555 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 278, 946, 31, 555 is 1.
Therefore, GCD of numbers 278, 946, 31, 555 is 1
Given Input Data is 278, 946, 31, 555
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 278 is 2 x 139
Prime Factorization of 946 is 2 x 11 x 43
Prime Factorization of 31 is 31
Prime Factorization of 555 is 3 x 5 x 37
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(278, 946) = 131494
GCD(278, 946) = ( 278 x 946 ) / 131494
GCD(278, 946) = 262988 / 131494
GCD(278, 946) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 31
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 31) = 62
GCD(2, 31) = ( 2 x 31 ) / 62
GCD(2, 31) = 62 / 62
GCD(2, 31) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 555
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 555) = 555
GCD(1, 555) = ( 1 x 555 ) / 555
GCD(1, 555) = 555 / 555
GCD(1, 555) = 1
GCD of 278, 946, 31, 555 is 1
