1, 2, 389, 778
Greatest Common Divisior
We found the divisors of 146, 965, 20, 778 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 146, 965, 20, 778 is 1.
Therefore, GCD of numbers 146, 965, 20, 778 is 1
Given Input Data is 146, 965, 20, 778
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 146 is 2 x 73
Prime Factorization of 965 is 5 x 193
Prime Factorization of 20 is 2 x 2 x 5
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(146, 965) = 140890
GCD(146, 965) = ( 146 x 965 ) / 140890
GCD(146, 965) = 140890 / 140890
GCD(146, 965) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 20
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
GCD(1, 20) = 20 / 20
GCD(1, 20) = 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 146, 965, 20, 778 is 1
