Given Input Data is 902, 615, 630, 689

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

Prime Factorization of 902 is 2 x 11 x 41

Prime Factorization of 615 is 3 x 5 x 41

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

Prime Factorization of 689 is 13 x 53

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(902, 615) = 13530

GCD(902, 615) = ( 902 x 615 ) / 13530

GCD(902, 615) = 554730 / 13530

GCD(902, 615) = 41

Step2:

Here we consider the GCD from the above i.e. 41 as first number and the next as 630

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

LCM(41, 630) = 25830

GCD(41, 630) = ( 41 x 630 ) / 25830

GCD(41, 630) = 25830 / 25830

GCD(41, 630) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 689

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

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

GCD(1, 689) = 689 / 689

GCD(1, 689) = 1

GCD of 902, 615, 630, 689 is 1
