Therefore, GCD of numbers 183, 393, 786, 203 is 1

Given Input Data is 183, 393, 786, 203

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

Prime Factorization of 183 is 3 x 61

Prime Factorization of 393 is 3 x 131

Prime Factorization of 786 is 2 x 3 x 131

Prime Factorization of 203 is 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(183, 393) = 23973

GCD(183, 393) = ( 183 x 393 ) / 23973

GCD(183, 393) = 71919 / 23973

GCD(183, 393) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 786

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

LCM(3, 786) = 786

GCD(3, 786) = ( 3 x 786 ) / 786

GCD(3, 786) = 2358 / 786

GCD(3, 786) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 203

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

LCM(3, 203) = 609

GCD(3, 203) = ( 3 x 203 ) / 609

GCD(3, 203) = 609 / 609

GCD(3, 203) = 1

GCD of 183, 393, 786, 203 is 1
