We found the divisors of 731, 754, 455, 747 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 731, 754, 455, 747 is 1.

Therefore, GCD of numbers 731, 754, 455, 747 is 1

Given Input Data is 731, 754, 455, 747

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

Prime Factorization of 731 is 17 x 43

Prime Factorization of 754 is 2 x 13 x 29

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 747 is 3 x 3 x 83

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(731, 754) = 551174

GCD(731, 754) = ( 731 x 754 ) / 551174

GCD(731, 754) = 551174 / 551174

GCD(731, 754) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 455

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

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

GCD(1, 455) = 455 / 455

GCD(1, 455) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 747

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

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

GCD(1, 747) = 747 / 747

GCD(1, 747) = 1

GCD of 731, 754, 455, 747 is 1
