So the Greatest Common Divisior 757, 330, 420, 440 is 1.

Therefore, GCD of numbers 757, 330, 420, 440 is 1

Given Input Data is 757, 330, 420, 440

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

Prime Factorization of 757 is 757

Prime Factorization of 330 is 2 x 3 x 5 x 11

Prime Factorization of 420 is 2 x 2 x 3 x 5 x 7

Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11

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(757, 330) = 249810

GCD(757, 330) = ( 757 x 330 ) / 249810

GCD(757, 330) = 249810 / 249810

GCD(757, 330) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 420

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

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

GCD(1, 420) = 420 / 420

GCD(1, 420) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 440

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

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

GCD(1, 440) = 440 / 440

GCD(1, 440) = 1

GCD of 757, 330, 420, 440 is 1
