Therefore, GCD of numbers 161, 525, 89, 618 is 1

Given Input Data is 161, 525, 89, 618

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

Prime Factorization of 161 is 7 x 23

Prime Factorization of 525 is 3 x 5 x 5 x 7

Prime Factorization of 89 is 89

Prime Factorization of 618 is 2 x 3 x 103

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(161, 525) = 12075

GCD(161, 525) = ( 161 x 525 ) / 12075

GCD(161, 525) = 84525 / 12075

GCD(161, 525) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 89

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

LCM(7, 89) = 623

GCD(7, 89) = ( 7 x 89 ) / 623

GCD(7, 89) = 623 / 623

GCD(7, 89) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 618

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

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

GCD(1, 618) = 618 / 618

GCD(1, 618) = 1

GCD of 161, 525, 89, 618 is 1
