We found the divisors of 257, 400, 701, 917 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 257, 400, 701, 917 is 1.

Therefore, GCD of numbers 257, 400, 701, 917 is 1

Given Input Data is 257, 400, 701, 917

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 257 is 257

Prime Factorization of 400 is 2 x 2 x 2 x 2 x 5 x 5

Prime Factorization of 701 is 701

Prime Factorization of 917 is 7 x 131

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(257, 400) = 102800

GCD(257, 400) = ( 257 x 400 ) / 102800

GCD(257, 400) = 102800 / 102800

GCD(257, 400) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 701

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 701) = 701

GCD(1, 701) = ( 1 x 701 ) / 701

GCD(1, 701) = 701 / 701

GCD(1, 701) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 917

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

GCD(1, 917) = 917 / 917

GCD(1, 917) = 1

GCD of 257, 400, 701, 917 is 1
