Finding GCD of 803, 117, 690, 647 using Prime Factorization

Given Input Data is 803, 117, 690, 647

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

Prime Factorization of 803 is 11 x 73

Prime Factorization of 117 is 3 x 3 x 13

Prime Factorization of 690 is 2 x 3 x 5 x 23

Prime Factorization of 647 is 647

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

Finding GCD of 803, 117, 690, 647 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(803, 117) = 93951

GCD(803, 117) = ( 803 x 117 ) / 93951

GCD(803, 117) = 93951 / 93951

GCD(803, 117) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 690

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

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

GCD(1, 690) = 690 / 690

GCD(1, 690) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 647

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

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

GCD(1, 647) = 647 / 647

GCD(1, 647) = 1

GCD of 803, 117, 690, 647 is 1
