Finding GCD of 630, 647, 40, 551 using Prime Factorization

Given Input Data is 630, 647, 40, 551

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

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 647 is 647

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 551 is 19 x 29

The above numbers do not have any common prime factor. So GCD is 1

Finding GCD of 630, 647, 40, 551 using LCM Formula

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(630, 647) = 407610

GCD(630, 647) = ( 630 x 647 ) / 407610

GCD(630, 647) = 407610 / 407610

GCD(630, 647) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 40

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

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

GCD(1, 40) = 40 / 40

GCD(1, 40) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 551

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

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

GCD(1, 551) = 551 / 551

GCD(1, 551) = 1

GCD of 630, 647, 40, 551 is 1
