Finding GCD of 690, 545, 252, 388 using Prime Factorization

Given Input Data is 690, 545, 252, 388

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

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

Prime Factorization of 545 is 5 x 109

Prime Factorization of 252 is 2 x 2 x 3 x 3 x 7

Prime Factorization of 388 is 2 x 2 x 97

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

Finding GCD of 690, 545, 252, 388 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(690, 545) = 75210

GCD(690, 545) = ( 690 x 545 ) / 75210

GCD(690, 545) = 376050 / 75210

GCD(690, 545) = 5


Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 252

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

LCM(5, 252) = 1260

GCD(5, 252) = ( 5 x 252 ) / 1260

GCD(5, 252) = 1260 / 1260

GCD(5, 252) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 388

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

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

GCD(1, 388) = 388 / 388

GCD(1, 388) = 1

GCD of 690, 545, 252, 388 is 1
