Therefore, GCD of numbers 183, 378, 87, 787 is 1

Given Input Data is 183, 378, 87, 787

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

Prime Factorization of 183 is 3 x 61

Prime Factorization of 378 is 2 x 3 x 3 x 3 x 7

Prime Factorization of 87 is 3 x 29

Prime Factorization of 787 is 787

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, 378) = 23058

GCD(183, 378) = ( 183 x 378 ) / 23058

GCD(183, 378) = 69174 / 23058

GCD(183, 378) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 87

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

LCM(3, 87) = 87

GCD(3, 87) = ( 3 x 87 ) / 87

GCD(3, 87) = 261 / 87

GCD(3, 87) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 787

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

LCM(3, 787) = 2361

GCD(3, 787) = ( 3 x 787 ) / 2361

GCD(3, 787) = 2361 / 2361

GCD(3, 787) = 1

GCD of 183, 378, 87, 787 is 1
