Greatest Common Divisior
We found the divisors of 155, 441, 193, 974 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 155, 441, 193, 974 is 1.
Therefore, GCD of numbers 155, 441, 193, 974 is 1
Given Input Data is 155, 441, 193, 974
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 155 is 5 x 31
Prime Factorization of 441 is 3 x 3 x 7 x 7
Prime Factorization of 193 is 193
Prime Factorization of 974 is 2 x 487
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(155, 441) = 68355
GCD(155, 441) = ( 155 x 441 ) / 68355
GCD(155, 441) = 68355 / 68355
GCD(155, 441) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 193
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
GCD(1, 193) = 193 / 193
GCD(1, 193) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 974
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 974) = 974
GCD(1, 974) = ( 1 x 974 ) / 974
GCD(1, 974) = 974 / 974
GCD(1, 974) = 1
GCD of 155, 441, 193, 974 is 1
