Therefore, GCD of numbers 651, 357, 490, 936 is 1

Given Input Data is 651, 357, 490, 936

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

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 357 is 3 x 7 x 17

Prime Factorization of 490 is 2 x 5 x 7 x 7

Prime Factorization of 936 is 2 x 2 x 2 x 3 x 3 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(651, 357) = 11067

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

GCD(651, 357) = 232407 / 11067

GCD(651, 357) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 490

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

LCM(21, 490) = 1470

GCD(21, 490) = ( 21 x 490 ) / 1470

GCD(21, 490) = 10290 / 1470

GCD(21, 490) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 936

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

LCM(7, 936) = 6552

GCD(7, 936) = ( 7 x 936 ) / 6552

GCD(7, 936) = 6552 / 6552

GCD(7, 936) = 1

GCD of 651, 357, 490, 936 is 1
