Therefore, GCD of numbers 42, 707, 603, 981 is 1

Given Input Data is 42, 707, 603, 981

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

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 707 is 7 x 101

Prime Factorization of 603 is 3 x 3 x 67

Prime Factorization of 981 is 3 x 3 x 109

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(42, 707) = 4242

GCD(42, 707) = ( 42 x 707 ) / 4242

GCD(42, 707) = 29694 / 4242

GCD(42, 707) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 603

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

LCM(7, 603) = 4221

GCD(7, 603) = ( 7 x 603 ) / 4221

GCD(7, 603) = 4221 / 4221

GCD(7, 603) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 981

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

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

GCD(1, 981) = 981 / 981

GCD(1, 981) = 1

GCD of 42, 707, 603, 981 is 1
