What number has only 6 factors?

So, 12 has six factors — 1, 2, 3, 4, 6, and 12 — but only two of them (2 and 3) are prime, so it has only two prime factors.

How do you find the sum of all even factors of a number?

Then Number of even factors of N = a * (b + 1) * (c + 1) … To get the sum of the even factors we need to ensure that all the terms in the expression for the sum of factors are even.

What is the sum of the factors of 6?

12
The sum of all factors of 6 is 12.

How do you find the number of even factors of a number?

positive integers. Ques 1 : Find the total number of even factors of 120. Solution : Prime Factorization of 120 is 120 = 23 × 31 × 51. Thus, Total number of even factors of 120 is (3)(1 + 1)(1 + 1) = 3 × 2 × 2 = 12.

How many factors does 6 have?

4 factors
Therefore, the number 6 has 4 factors.

What are factors 6?

The factors of 6 are 1, 2, 3 and 6.

How many even factors Does 360 have?

2
360 is an even number, hence, it has 2 as one of its factors. The last digit of 360 is 0. Thus, it has 1, 2, 5 and 10 as its factors.

What does a factor of 6 mean?

more Numbers we can multiply together to get another number. Example: 2 and 3 are factors of 6, because 2 × 3 = 6.

What are three multiples of 6?

Here again are the multiples of 6, 0, 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96,…

What is the sum of even factors with odd numbers?

It can be written as 2 1 3 2 and sun of all factors is (2 0 + 2 1 )* (3 0 + 3 1 + 3 2 ). if we remove 2 0 then we get the Sum of even factors (2)* (1+3+3 2) = 26. To remove odd number in even factor, we ignore then 2 0 whaich is 1. After this step, we only get even factors.

How to find the sum of factors of a number?

As discussed in above mentioned previous post, sum of factors of a number is Let p1, p2, … pk be prime factors of n. Let a1, a2, .. ak be highest powers of p1, p2, .. pk respectively that divide n, i.e., we can write n as n = (p1a1)* (p2a2)* … (pkak).

How to remove odd numbers from an even factor?

To remove odd number in even factor, we ignore then 2 0 whaich is 1. After this step, we only get even factors. Note that 2 is the only even prime. Below is the implementation of the above approach.

How do you know if a number is odd or even?

If number is odd, then there are no even factors, so we simply return 0. If number is even, we use above formula. We only need to ignore 2 0. All other terms multiply to produce even factor sum.
