Therefore, GCD of numbers 147, 686, 62, 429 is 1

Given Input Data is 147, 686, 62, 429

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

Prime Factorization of 147 is 3 x 7 x 7

Prime Factorization of 686 is 2 x 7 x 7 x 7

Prime Factorization of 62 is 2 x 31

Prime Factorization of 429 is 3 x 11 x 13

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(147, 686) = 2058

GCD(147, 686) = ( 147 x 686 ) / 2058

GCD(147, 686) = 100842 / 2058

GCD(147, 686) = 49

Step2:

Here we consider the GCD from the above i.e. 49 as first number and the next as 62

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

LCM(49, 62) = 3038

GCD(49, 62) = ( 49 x 62 ) / 3038

GCD(49, 62) = 3038 / 3038

GCD(49, 62) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 429

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

LCM(1, 429) = 429

GCD(1, 429) = ( 1 x 429 ) / 429

GCD(1, 429) = 429 / 429

GCD(1, 429) = 1

GCD of 147, 686, 62, 429 is 1
