Therefore, GCD of numbers 651, 310, 767, 215 is 1

Given Input Data is 651, 310, 767, 215

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

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 310 is 2 x 5 x 31

Prime Factorization of 767 is 13 x 59

Prime Factorization of 215 is 5 x 43

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(651, 310) = 6510

GCD(651, 310) = ( 651 x 310 ) / 6510

GCD(651, 310) = 201810 / 6510

GCD(651, 310) = 31

Step2:

Here we consider the GCD from the above i.e. 31 as first number and the next as 767

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

LCM(31, 767) = 23777

GCD(31, 767) = ( 31 x 767 ) / 23777

GCD(31, 767) = 23777 / 23777

GCD(31, 767) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 215

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

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

GCD(1, 215) = 215 / 215

GCD(1, 215) = 1

GCD of 651, 310, 767, 215 is 1
