Make use of GCD Calculator to determine the Greatest Common Divisor of 666, 136, 55, 389 i.e. 1 largest integer that divides all the numbers equally.
GCD of 666, 136, 55, 389 is 1
GCD(666, 136, 55, 389) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 666, 136, 55, 389 is 1
GCD(666, 136, 55, 389) = 1
Given Input numbers are 666, 136, 55, 389
To find the GCD of numbers using factoring list out all the divisors of each number

1, 389
Greatest Common Divisior
We found the divisors of 666, 136, 55, 389 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 666, 136, 55, 389 is 1.
Therefore, GCD of numbers 666, 136, 55, 389 is 1
Given Input Data is 666, 136, 55, 389
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 666 is 2 x 3 x 3 x 37
Prime Factorization of 136 is 2 x 2 x 2 x 17
Prime Factorization of 55 is 5 x 11
Prime Factorization of 389 is 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(666, 136) = 45288
GCD(666, 136) = ( 666 x 136 ) / 45288
GCD(666, 136) = 90576 / 45288
GCD(666, 136) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 55
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 55) = 110
GCD(2, 55) = ( 2 x 55 ) / 110
GCD(2, 55) = 110 / 110
GCD(2, 55) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 389
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
GCD(1, 389) = 389 / 389
GCD(1, 389) = 1
GCD of 666, 136, 55, 389 is 1
