Therefore, GCD of numbers 616, 143, 42, 387 is 1

Given Input Data is 616, 143, 42, 387

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

Prime Factorization of 616 is 2 x 2 x 2 x 7 x 11

Prime Factorization of 143 is 11 x 13

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 387 is 3 x 3 x 43

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(616, 143) = 8008

GCD(616, 143) = ( 616 x 143 ) / 8008

GCD(616, 143) = 88088 / 8008

GCD(616, 143) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 42

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

LCM(11, 42) = 462

GCD(11, 42) = ( 11 x 42 ) / 462

GCD(11, 42) = 462 / 462

GCD(11, 42) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 387

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

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

GCD(1, 387) = 387 / 387

GCD(1, 387) = 1

GCD of 616, 143, 42, 387 is 1
