Therefore, GCD of numbers 69, 519, 658, 105 is 1

Given Input Data is 69, 519, 658, 105

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

Prime Factorization of 69 is 3 x 23

Prime Factorization of 519 is 3 x 173

Prime Factorization of 658 is 2 x 7 x 47

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(69, 519) = 11937

GCD(69, 519) = ( 69 x 519 ) / 11937

GCD(69, 519) = 35811 / 11937

GCD(69, 519) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 658

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

LCM(3, 658) = 1974

GCD(3, 658) = ( 3 x 658 ) / 1974

GCD(3, 658) = 1974 / 1974

GCD(3, 658) = 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 69, 519, 658, 105 is 1
