Also, how do you find the number of positive integer factors?

To find the number of factors of a given number, express the number as a product of powers of prime numbers. Now, increment the power of each of the prime numbers by 1 and multiply the result. Therefore, there will 10 factors including 1 and 48. Excluding, these two numbers, you will have 10 - 2 = 8 factors.

One may also ask, what is the number of factors? "Factors" are the numbers you multiply to get another number. For instance, factors of 15 are 3 and 5, because 3×5 = 15. Some numbers have more than one factorization (more than one way of being factored). For instance, 12 can be factored as 1×12, 2×6, or 3×4.

Keeping this in view, how many positive integers are there?

So there are Six three-digit positive integers that can be formed from the digits 3 , 4 , and 8 . In fact, we could list them all if we really wanted to: 348 , 384 , 438 , 483 , 834 , and 843 .

How many positive factors of 120 are there?

120 = 1 x 120, 2 x 60, 3 x 40, 4 x 30, 5 x 24, 6 x 20, 8 x 15, or 10 x 12. Factors of 120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120. Prime factorization: 120 = 2 x 2 x 2 x 3 x 5, which can also be written 120 = 2³ x 3 x 5.
