Therefore, GCD of numbers 85, 570, 658, 495 is 1

Given Input Data is 85, 570, 658, 495

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

Prime Factorization of 85 is 5 x 17

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 658 is 2 x 7 x 47

Prime Factorization of 495 is 3 x 3 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(85, 570) = 9690

GCD(85, 570) = ( 85 x 570 ) / 9690

GCD(85, 570) = 48450 / 9690

GCD(85, 570) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 658

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

LCM(5, 658) = 3290

GCD(5, 658) = ( 5 x 658 ) / 3290

GCD(5, 658) = 3290 / 3290

GCD(5, 658) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 495

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

LCM(1, 495) = 495

GCD(1, 495) = ( 1 x 495 ) / 495

GCD(1, 495) = 495 / 495

GCD(1, 495) = 1

GCD of 85, 570, 658, 495 is 1
