Greatest Common Divisior
We found the divisors of 657, 278, 451 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 657, 278, 451 is 1.
Therefore, GCD of numbers 657, 278, 451 is 1
Given Input Data is 657, 278, 451
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 657 is 3 x 3 x 73
Prime Factorization of 278 is 2 x 139
Prime Factorization of 451 is 11 x 41
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(657, 278) = 182646
GCD(657, 278) = ( 657 x 278 ) / 182646
GCD(657, 278) = 182646 / 182646
GCD(657, 278) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 451
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 451) = 451
GCD(1, 451) = ( 1 x 451 ) / 451
GCD(1, 451) = 451 / 451
GCD(1, 451) = 1
GCD of 657, 278, 451 is 1
