To find the total number of factors for any integer, we first determine its prime factorization.
The prime factorization of a number $N$ is expressed as $N = p_1^{a_1} \times p_2^{a_2} \times \dots \times p_k^{a_k}$, where $p_i$ are distinct prime numbers and $a_i$ are their positive integer exponents.
The total number of factors of $N$ is calculated using the formula: Number of Factors = $(a_1+1)(a_2+1)\dots(a_k+1)$.
Let's find the prime factors of 12288:
The prime factorization of 12288 is $2^{12} \times 3^1$.
Using the prime factorization $12288 = 2^{12} \times 3^1$, we identify the exponents:
Apply the formula for the number of factors:
Number of Factors = $(12 + 1) \times (1 + 1)$
Number of Factors = $13 \times 2$
Number of Factors = $26$
Thus, the number 12288 has 26 factors.
Express 486 as a product of powers of prime factors.
Let p, q, r and s be positive natural numbers having three exact factors including 1 and the number itself. If q > p and both are two-digit numbers, and r > s and both are one-digit numbers, then the value of the expression \(\frac{p-q-1}{r-s}\) is:
