In Mathematics, the factors of a number are all the integers that can divide that number exactly, leaving a remainder of zero. Let's find all the factors of the number 15.
Factors of 15: 1, 3, 5, 15.
Total number of factors: 4.
Prime factors: 3 and 5.
Type: 15 is an Odd Composite Number (because it has more than 2 factors).
To find the factors, we look for pairs of numbers that multiply together to give 15:
Therefore, the factors of 15 are: 1, 3, 5, and 15.
A factor pair is a set of two numbers that multiply to give 15. Since multiplying two negative numbers gives a positive product, we have positive and negative pairs:
Prime factorization means breaking down the number into a set of prime numbers that multiply together to give the original number.
Prime Factorization of 15 = 3 × 5 (Note: 1 is not a prime number, so it is never included in prime factorization).
The factors of 15 are the numbers 1, 3, 5, and 15.
The prime factorization of 15 is 3 × 5.
Expand log₁₀(385)
log₁₀(385) = log₁₀5 + log₁₀7 + log₁₀11. Since 385 = 5 × 7 × 11, apply log(ab) = log a + log b. Learn with full working and log laws.
