We found the divisors of 160, 138, 23, 465 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 160, 138, 23, 465 is 1.

Therefore, GCD of numbers 160, 138, 23, 465 is 1

Given Input Data is 160, 138, 23, 465

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

Prime Factorization of 160 is 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 138 is 2 x 3 x 23

Prime Factorization of 23 is 23

Prime Factorization of 465 is 3 x 5 x 31

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(160, 138) = 11040

GCD(160, 138) = ( 160 x 138 ) / 11040

GCD(160, 138) = 22080 / 11040

GCD(160, 138) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 23

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

LCM(2, 23) = 46

GCD(2, 23) = ( 2 x 23 ) / 46

GCD(2, 23) = 46 / 46

GCD(2, 23) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 465

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

LCM(1, 465) = 465

GCD(1, 465) = ( 1 x 465 ) / 465

GCD(1, 465) = 465 / 465

GCD(1, 465) = 1

GCD of 160, 138, 23, 465 is 1
