Therefore, GCD of numbers 840, 658, 546, 503 is 1

Given Input Data is 840, 658, 546, 503

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

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

Prime Factorization of 658 is 2 x 7 x 47

Prime Factorization of 546 is 2 x 3 x 7 x 13

Prime Factorization of 503 is 503

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(840, 658) = 39480

GCD(840, 658) = ( 840 x 658 ) / 39480

GCD(840, 658) = 552720 / 39480

GCD(840, 658) = 14

Step2:

Here we consider the GCD from the above i.e. 14 as first number and the next as 546

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

LCM(14, 546) = 546

GCD(14, 546) = ( 14 x 546 ) / 546

GCD(14, 546) = 7644 / 546

GCD(14, 546) = 14

Step3:

Here we consider the GCD from the above i.e. 14 as first number and the next as 503

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

LCM(14, 503) = 7042

GCD(14, 503) = ( 14 x 503 ) / 7042

GCD(14, 503) = 7042 / 7042

GCD(14, 503) = 1

GCD of 840, 658, 546, 503 is 1
