Therefore, GCD of numbers 172, 620, 64, 233 is 1

Given Input Data is 172, 620, 64, 233

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

Prime Factorization of 172 is 2 x 2 x 43

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 233 is 233

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(172, 620) = 26660

GCD(172, 620) = ( 172 x 620 ) / 26660

GCD(172, 620) = 106640 / 26660

GCD(172, 620) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 64

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

LCM(4, 64) = 64

GCD(4, 64) = ( 4 x 64 ) / 64

GCD(4, 64) = 256 / 64

GCD(4, 64) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 233

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

LCM(4, 233) = 932

GCD(4, 233) = ( 4 x 233 ) / 932

GCD(4, 233) = 932 / 932

GCD(4, 233) = 1

GCD of 172, 620, 64, 233 is 1
