The prime factorization of 54 is 2 x 3 x 3 x 3, which can also be written as 2 x 3^{3}. Prime factors are the prime numbers that are multiplied to get another number. A prime number is any number that can only be divided by itself and 1, such as 3, 5 and 17; numbers that can be divided by other numbers are called composite numbers.
Know MoreThe only even number that is a prime number is 2, and 2 is a prime factor of every even number. Therefore, to find the prime factors of 54, the first step is to divide by 2. This results in 27, which cannot be divided by 2. The next step is to determine whether 27 can be further divided. When it is divided by 3, the result is 9. Since 3 is a prime number, it is the second prime factor of 54. The number 9 can be further divided into 3 x 3. The full prime factorization of 54 is 2 x 3 x 3 x 3.
Prime numbers can be considered the building blocks of numbers. Every number has its own unique set of prime factors. This fact is known as the Fundamental Theorem of Arithmetic. Prime factorization is useful in cryptology and computer encryption because it can take a long time for computers to determine the set of prime factors for large numbers.
Learn MoreThe number 67 is a prime number by definition. A prime number is any positive number that can only be divided evenly by the number one and itself. It must also be a whole number greater than one, no fractions or decimals.
Full Answer >Mathematical equations called functions use input and output replace the variables in an equation. The input is the known variable, while the output is the solution. Use functions any time a variable (x) transforms in a relationship to equal a new variable (y).
Full Answer >The equivalent of 401 in Roman numerals is CDI. The Roman numeral system uses letters rather than numerals. The basic letters and their numeric equivalents are as follows: I equals one, V equals five, X equals 10, L equals 50, C equals 100, D equals 500 and M equals 1,000.
Full Answer >One billion in numerals is written as 1,000,000,000. To write one billion in numerals, you will need ten figures before the decimal point. For example, seven billion translates to 7,000,000,000.
