Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves without leaving a remainder. Prime factors of a number are its factors that are prime numbers themselves. To find the prime factors of a number, one can use a prime factor tree by repeatedly dividing the number by its prime factors until only prime numbers remain. For example, the prime factors of 60 are 2, 2, 3, and 5.
2. A prime number is a number greater than 1 with only two
factors themselves and 1.
A prime number cannot be divided by any other numbers
without leaving a remainder
An example of a prime number is 13.
3. Prime factors are factors of a number that are, themselves,
prime numbers.
There are many methods to find the prime
factors of a number, but one of the most
common is to use a prime factor tree.
For example 60
You do what two numbers times to give 60 and
2 and 30 - you will circle the 2 because it is a prime number then
you find 2 numbers timed. Together that give 30. 6 and 5 you will
circle 5 then you find 2 numbers that give 6 lke 3 and 2 then you
circle them both
4. 1 can only be divided by one number, 1 itself, so with this
definition 1 is not a prime number
It is important to remember that mathematical definitions
develop and evolve
Throughout history, many mathematicians considered 1 to be a
prime number although that is not now a commonly held view.
