Greatest Common Divisior
We found the divisors of 861, 890, 188, 150 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 861, 890, 188, 150 is 1.
Therefore, GCD of numbers 861, 890, 188, 150 is 1
Given Input Data is 861, 890, 188, 150
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 861 is 3 x 7 x 41
Prime Factorization of 890 is 2 x 5 x 89
Prime Factorization of 188 is 2 x 2 x 47
Prime Factorization of 150 is 2 x 3 x 5 x 5
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(861, 890) = 766290
GCD(861, 890) = ( 861 x 890 ) / 766290
GCD(861, 890) = 766290 / 766290
GCD(861, 890) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 188
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 188) = 188
GCD(1, 188) = ( 1 x 188 ) / 188
GCD(1, 188) = 188 / 188
GCD(1, 188) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 150
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 150) = 150
GCD(1, 150) = ( 1 x 150 ) / 150
GCD(1, 150) = 150 / 150
GCD(1, 150) = 1
GCD of 861, 890, 188, 150 is 1
