Greatest Common Divisior
We found the divisors of 128, 486, 373, 660 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 128, 486, 373, 660 is 1.
Therefore, GCD of numbers 128, 486, 373, 660 is 1
Given Input Data is 128, 486, 373, 660
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2
Prime Factorization of 486 is 2 x 3 x 3 x 3 x 3 x 3
Prime Factorization of 373 is 373
Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11
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(128, 486) = 31104
GCD(128, 486) = ( 128 x 486 ) / 31104
GCD(128, 486) = 62208 / 31104
GCD(128, 486) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 373
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 373) = 746
GCD(2, 373) = ( 2 x 373 ) / 746
GCD(2, 373) = 746 / 746
GCD(2, 373) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 660
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
GCD(1, 660) = 660 / 660
GCD(1, 660) = 1
GCD of 128, 486, 373, 660 is 1
