1, 2, 389, 778
Greatest Common Divisior
We found the divisors of 239, 490, 956, 778 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 239, 490, 956, 778 is 1.
Therefore, GCD of numbers 239, 490, 956, 778 is 1
Given Input Data is 239, 490, 956, 778
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 239 is 239
Prime Factorization of 490 is 2 x 5 x 7 x 7
Prime Factorization of 956 is 2 x 2 x 239
Prime Factorization of 778 is 2 x 389
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(239, 490) = 117110
GCD(239, 490) = ( 239 x 490 ) / 117110
GCD(239, 490) = 117110 / 117110
GCD(239, 490) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 956
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 956) = 956
GCD(1, 956) = ( 1 x 956 ) / 956
GCD(1, 956) = 956 / 956
GCD(1, 956) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 778
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
GCD(1, 778) = 778 / 778
GCD(1, 778) = 1
GCD of 239, 490, 956, 778 is 1
