Therefore, GCD of numbers 658, 504, 17, 435 is 1

Given Input Data is 658, 504, 17, 435

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

Prime Factorization of 658 is 2 x 7 x 47

Prime Factorization of 504 is 2 x 2 x 2 x 3 x 3 x 7

Prime Factorization of 17 is 17

Prime Factorization of 435 is 3 x 5 x 29

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(658, 504) = 23688

GCD(658, 504) = ( 658 x 504 ) / 23688

GCD(658, 504) = 331632 / 23688

GCD(658, 504) = 14

Step2:

Here we consider the GCD from the above i.e. 14 as first number and the next as 17

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

LCM(14, 17) = 238

GCD(14, 17) = ( 14 x 17 ) / 238

GCD(14, 17) = 238 / 238

GCD(14, 17) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 435

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

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

GCD(1, 435) = 435 / 435

GCD(1, 435) = 1

GCD of 658, 504, 17, 435 is 1
