Therefore, GCD of numbers 357, 651, 48, 643 is 1

Given Input Data is 357, 651, 48, 643

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

Prime Factorization of 357 is 3 x 7 x 17

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 48 is 2 x 2 x 2 x 2 x 3

Prime Factorization of 643 is 643

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(357, 651) = 11067

GCD(357, 651) = ( 357 x 651 ) / 11067

GCD(357, 651) = 232407 / 11067

GCD(357, 651) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 48

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

LCM(21, 48) = 336

GCD(21, 48) = ( 21 x 48 ) / 336

GCD(21, 48) = 1008 / 336

GCD(21, 48) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 643

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

LCM(3, 643) = 1929

GCD(3, 643) = ( 3 x 643 ) / 1929

GCD(3, 643) = 1929 / 1929

GCD(3, 643) = 1

GCD of 357, 651, 48, 643 is 1
