We found the divisors of 761, 842, 78, 603 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 761, 842, 78, 603 is 1.

Therefore, GCD of numbers 761, 842, 78, 603 is 1

Given Input Data is 761, 842, 78, 603

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

Prime Factorization of 761 is 761

Prime Factorization of 842 is 2 x 421

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 603 is 3 x 3 x 67

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(761, 842) = 640762

GCD(761, 842) = ( 761 x 842 ) / 640762

GCD(761, 842) = 640762 / 640762

GCD(761, 842) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 78

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

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

GCD(1, 78) = 78 / 78

GCD(1, 78) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 603

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

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

GCD(1, 603) = 603 / 603

GCD(1, 603) = 1

GCD of 761, 842, 78, 603 is 1
