8 factors
130 is a composite number. There are a total of 8 factors of 130. Among the 8 factors, 3 are prime factors.
Is there a perfect square in 113?
The square root of 113 is irrational. 113 is not a perfect square which makes it difficult to simplify √113 any further.
How many numbers from 1 to 100 have exactly 3 factors?
The factors must be prime, since any non-prime factor would itself have factors, meaning we’d exclude for example 2 x 3 x 4 = 24 since 4 is 2 x 2, so 24 really has 4 factors. Prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 – anything over this cannot result in a combined result of 100 or less (since 2 x 2 x n = 100 gives n = 25).
What are two numbers less than 50 that have exactly 3 factors?
You should have probably mentioned “2 digit numbers less than 50 that have exactly 3 factors”, because this is the property of a square number of a prime and there are 4 squares below 50 that are the squares of prime numbers. There are 4 numbers as shown below and two of them are 2 digit numbers and the remaining 2 numbers are single digit numbers.
How to calculate the factors of a number?
Click “Calculate” to see all factors of each number as well as the greatest common factor (GCF). The factors of a number include all divisors of that number. The factors of 12, for example, are 1, 2, 3, 4, 6 and 12.
Is it possible for a number to have multiple factors?
It is possible for a number to have multiple factors. Using 12 as an example, in addition to 3 and 4 being factors: It can be seen that 1, 2, 3, 4, 6, and 12 are all factors of the number 12. This is the most basic form of a factor, but algebraic expressions can also be factored, though that is not the intent of this calculator.
