Therefore, GCD of numbers 77, 903, 603, 635 is 1

Given Input Data is 77, 903, 603, 635

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

Prime Factorization of 77 is 7 x 11

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 603 is 3 x 3 x 67

Prime Factorization of 635 is 5 x 127

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(77, 903) = 9933

GCD(77, 903) = ( 77 x 903 ) / 9933

GCD(77, 903) = 69531 / 9933

GCD(77, 903) = 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 635

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

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

GCD(1, 635) = 635 / 635

GCD(1, 635) = 1

GCD of 77, 903, 603, 635 is 1
