We found the divisors of 605, 651, 63, 749 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 605, 651, 63, 749 is 1.

Therefore, GCD of numbers 605, 651, 63, 749 is 1

Given Input Data is 605, 651, 63, 749

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

Prime Factorization of 605 is 5 x 11 x 11

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 749 is 7 x 107

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(605, 651) = 393855

GCD(605, 651) = ( 605 x 651 ) / 393855

GCD(605, 651) = 393855 / 393855

GCD(605, 651) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 63

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

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

GCD(1, 63) = 63 / 63

GCD(1, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 749

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

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

GCD(1, 749) = 749 / 749

GCD(1, 749) = 1

GCD of 605, 651, 63, 749 is 1
