The factors the 8 space the numbers that divide 8 precisely without leaving any kind of remainder. There are four determinants of 8, they are 1, 2, 4, and also 8. Hence, the highest element is 8 the divides itself. If we add all the factors, climate the amount will be equal to 15. 

The pair components of 8 are (1,8) and (2,4). These pair factors when multiplied together results in the initial number. 8 is additionally a perfect cube, thus its prime element will it is in a solitary digit. We have the right to determine the determinants of 8 by the department method and prime factorisation method.

How to Find factors of 8?

8 is a whole number that is additionally an even number. Due to the fact that it is a single-digit number, therefore, the is much easier to find the components of 8.

There are two methods to uncover the components of 8:

Division methodPrime factorisation method

Factors the 8 by department Method

The components of 8 deserve to be found using the department method. In the division method, we need to uncover the integers which division 8 specifically without leave a remainder, and also those integers are considered as the components of 8. Now, allow us discover the determinants of 8 using the department method.

8/1 = 8 (Factor is 1 and also Remainder is 0)8/2 = 4 (Factor is 2 and also Remainder is 0)8/4 = 2 (Factor is 4 and also Remainder is 0)8/8 = 1 (Factor is 8 and Remainder is 0)

If we divide 8 by any numbers other than 1, 2, 8 and 8, it pipeline a remainder. Hence, the factors of 8 space 1, 2, 4 and also 8.

Prime factorization of 8

The prime factorization of 8 is the procedure of writing the number as the product that its prime factors. Now, let us comment on the procedure of finding the prime components of 8.

Divide 8 by the the smallest prime number, i.e. 2. 8/2 = 4Divide 4 by the smallest feasible prime number, 4/2 = 22 is itself a prime number and is divisible by 2Therefore, the prime administer of 8 is 2 × 2 × 2 or 23.

Another an approach to find the prime factors of 8 is the element tree method.

Hence, the variety of prime components of 8 is one. The prime factorisation that the whole number 8 is 23. The exponent in the element factorisation is 3. Once you include the number 1 through the exponent, i.e.,3 +1 = 4. Therefore, the number 8 has 4 factors.
