Greatest Common Divisior
We found the divisors of 969, 178, 550, 155 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 969, 178, 550, 155 is 1.
Therefore, GCD of numbers 969, 178, 550, 155 is 1
Given Input Data is 969, 178, 550, 155
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 969 is 3 x 17 x 19
Prime Factorization of 178 is 2 x 89
Prime Factorization of 550 is 2 x 5 x 5 x 11
Prime Factorization of 155 is 5 x 31
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(969, 178) = 172482
GCD(969, 178) = ( 969 x 178 ) / 172482
GCD(969, 178) = 172482 / 172482
GCD(969, 178) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 550
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 550) = 550
GCD(1, 550) = ( 1 x 550 ) / 550
GCD(1, 550) = 550 / 550
GCD(1, 550) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 155
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
GCD(1, 155) = 155 / 155
GCD(1, 155) = 1
GCD of 969, 178, 550, 155 is 1
