Therefore, GCD of numbers 724, 188, 155, 609 is 1

Given Input Data is 724, 188, 155, 609

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

Prime Factorization of 724 is 2 x 2 x 181

Prime Factorization of 188 is 2 x 2 x 47

Prime Factorization of 155 is 5 x 31

Prime Factorization of 609 is 3 x 7 x 29

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(724, 188) = 34028

GCD(724, 188) = ( 724 x 188 ) / 34028

GCD(724, 188) = 136112 / 34028

GCD(724, 188) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 155

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

LCM(4, 155) = 620

GCD(4, 155) = ( 4 x 155 ) / 620

GCD(4, 155) = 620 / 620

GCD(4, 155) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 609

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

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

GCD(1, 609) = 609 / 609

GCD(1, 609) = 1

GCD of 724, 188, 155, 609 is 1
