Given Input Data is 658, 931, 153, 890

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

Prime Factorization of 658 is 2 x 7 x 47

Prime Factorization of 931 is 7 x 7 x 19

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 890 is 2 x 5 x 89

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(658, 931) = 87514

GCD(658, 931) = ( 658 x 931 ) / 87514

GCD(658, 931) = 612598 / 87514

GCD(658, 931) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 153

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

LCM(7, 153) = 1071

GCD(7, 153) = ( 7 x 153 ) / 1071

GCD(7, 153) = 1071 / 1071

GCD(7, 153) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 890

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

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

GCD(1, 890) = 890 / 890

GCD(1, 890) = 1

GCD of 658, 931, 153, 890 is 1
