We found the divisors of 453, 412, 761, 646 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 453, 412, 761, 646 is 1.

Therefore, GCD of numbers 453, 412, 761, 646 is 1

Given Input Data is 453, 412, 761, 646

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

Prime Factorization of 453 is 3 x 151

Prime Factorization of 412 is 2 x 2 x 103

Prime Factorization of 761 is 761

Prime Factorization of 646 is 2 x 17 x 19

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(453, 412) = 186636

GCD(453, 412) = ( 453 x 412 ) / 186636

GCD(453, 412) = 186636 / 186636

GCD(453, 412) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 761

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

LCM(1, 761) = 761

GCD(1, 761) = ( 1 x 761 ) / 761

GCD(1, 761) = 761 / 761

GCD(1, 761) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 646

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

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

GCD(1, 646) = 646 / 646

GCD(1, 646) = 1

GCD of 453, 412, 761, 646 is 1
