Greatest Common Divisior
We found the divisors of 628, 566, 657, 143 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 628, 566, 657, 143 is 1.
Therefore, GCD of numbers 628, 566, 657, 143 is 1
Given Input Data is 628, 566, 657, 143
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 628 is 2 x 2 x 157
Prime Factorization of 566 is 2 x 283
Prime Factorization of 657 is 3 x 3 x 73
Prime Factorization of 143 is 11 x 13
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(628, 566) = 177724
GCD(628, 566) = ( 628 x 566 ) / 177724
GCD(628, 566) = 355448 / 177724
GCD(628, 566) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 657
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 657) = 1314
GCD(2, 657) = ( 2 x 657 ) / 1314
GCD(2, 657) = 1314 / 1314
GCD(2, 657) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 143
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 143) = 143
GCD(1, 143) = ( 1 x 143 ) / 143
GCD(1, 143) = 143 / 143
GCD(1, 143) = 1
GCD of 628, 566, 657, 143 is 1
