Finding GCD of 217, 210, 68, 807 using Prime Factorization

Given Input Data is 217, 210, 68, 807

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

Prime Factorization of 217 is 7 x 31

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 807 is 3 x 269

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

Finding GCD of 217, 210, 68, 807 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(217, 210) = 6510

GCD(217, 210) = ( 217 x 210 ) / 6510

GCD(217, 210) = 45570 / 6510

GCD(217, 210) = 7


Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 68

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

LCM(7, 68) = 476

GCD(7, 68) = ( 7 x 68 ) / 476

GCD(7, 68) = 476 / 476

GCD(7, 68) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 807

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

LCM(1, 807) = 807

GCD(1, 807) = ( 1 x 807 ) / 807

GCD(1, 807) = 807 / 807

GCD(1, 807) = 1

GCD of 217, 210, 68, 807 is 1
