So the Greatest Common Divisior 491, 752, 455, 161 is 1.

Therefore, GCD of numbers 491, 752, 455, 161 is 1

Given Input Data is 491, 752, 455, 161

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

Prime Factorization of 491 is 491

Prime Factorization of 752 is 2 x 2 x 2 x 2 x 47

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 161 is 7 x 23

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(491, 752) = 369232

GCD(491, 752) = ( 491 x 752 ) / 369232

GCD(491, 752) = 369232 / 369232

GCD(491, 752) = 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 161

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

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

GCD(1, 161) = 161 / 161

GCD(1, 161) = 1

GCD of 491, 752, 455, 161 is 1
