Therefore, GCD of numbers 690, 651, 502, 246 is 1

Given Input Data is 690, 651, 502, 246

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 651 is 3 x 7 x 31

Prime Factorization of 502 is 2 x 251

Prime Factorization of 246 is 2 x 3 x 41

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(690, 651) = 149730

GCD(690, 651) = ( 690 x 651 ) / 149730

GCD(690, 651) = 449190 / 149730

GCD(690, 651) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 502

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

LCM(3, 502) = 1506

GCD(3, 502) = ( 3 x 502 ) / 1506

GCD(3, 502) = 1506 / 1506

GCD(3, 502) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 246

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

LCM(1, 246) = 246

GCD(1, 246) = ( 1 x 246 ) / 246

GCD(1, 246) = 246 / 246

GCD(1, 246) = 1

GCD of 690, 651, 502, 246 is 1
