We found the divisors of 634, 490, 127, 105 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 634, 490, 127, 105 is 1.

Therefore, GCD of numbers 634, 490, 127, 105 is 1

Given Input Data is 634, 490, 127, 105

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

Prime Factorization of 634 is 2 x 317

Prime Factorization of 490 is 2 x 5 x 7 x 7

Prime Factorization of 127 is 127

Prime Factorization of 105 is 3 x 5 x 7

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(634, 490) = 155330

GCD(634, 490) = ( 634 x 490 ) / 155330

GCD(634, 490) = 310660 / 155330

GCD(634, 490) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 127

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

LCM(2, 127) = 254

GCD(2, 127) = ( 2 x 127 ) / 254

GCD(2, 127) = 254 / 254

GCD(2, 127) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 105

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

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

GCD(1, 105) = 105 / 105

GCD(1, 105) = 1

GCD of 634, 490, 127, 105 is 1
