Therefore, GCD of numbers 619, 382, 490, 668 is 1

Given Input Data is 619, 382, 490, 668

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

Prime Factorization of 619 is 619

Prime Factorization of 382 is 2 x 191

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

Prime Factorization of 668 is 2 x 2 x 167

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(619, 382) = 236458

GCD(619, 382) = ( 619 x 382 ) / 236458

GCD(619, 382) = 236458 / 236458

GCD(619, 382) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 490

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

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

GCD(1, 490) = 490 / 490

GCD(1, 490) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 668

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

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

GCD(1, 668) = 668 / 668

GCD(1, 668) = 1

GCD of 619, 382, 490, 668 is 1
