1, 743
Greatest Common Divisior
We found the divisors of 258, 455, 248, 743 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 258, 455, 248, 743 is 1.
Therefore, GCD of numbers 258, 455, 248, 743 is 1
Given Input Data is 258, 455, 248, 743
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 258 is 2 x 3 x 43
Prime Factorization of 455 is 5 x 7 x 13
Prime Factorization of 248 is 2 x 2 x 2 x 31
Prime Factorization of 743 is 743
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(258, 455) = 117390
GCD(258, 455) = ( 258 x 455 ) / 117390
GCD(258, 455) = 117390 / 117390
GCD(258, 455) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 248
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 248) = 248
GCD(1, 248) = ( 1 x 248 ) / 248
GCD(1, 248) = 248 / 248
GCD(1, 248) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 743
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 743) = 743
GCD(1, 743) = ( 1 x 743 ) / 743
GCD(1, 743) = 743 / 743
GCD(1, 743) = 1
GCD of 258, 455, 248, 743 is 1
