Therefore, GCD of numbers 987, 201, 62, 690 is 1

Given Input Data is 987, 201, 62, 690

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

Prime Factorization of 987 is 3 x 7 x 47

Prime Factorization of 201 is 3 x 67

Prime Factorization of 62 is 2 x 31

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

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(987, 201) = 66129

GCD(987, 201) = ( 987 x 201 ) / 66129

GCD(987, 201) = 198387 / 66129

GCD(987, 201) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 62

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

LCM(3, 62) = 186

GCD(3, 62) = ( 3 x 62 ) / 186

GCD(3, 62) = 186 / 186

GCD(3, 62) = 1

Step3:

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

GCD of 987, 201, 62, 690 is 1
