All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.
Example: 210
210 Divide by two.
105,2 Divide by three.
35,3,2 Divide by five.
7,5,3,2 Stop. All the factors are prime.
2 x 3 x 5 x 7 = 210
That's the prime factorization of 210.

How do you factorize a prime number in index notation form?
Prime numbers don't factorize; they're already prime.
What can you learn about prime and composite number while playing the factor game?
If you play the factor game, you factorize the number. If the number of factors are only 2 including 1 and number itself, then it is a prime.
How do you factorize 10?
break it into prime number multiples,10 = 2 * 5 (both prime numbers)example: factorize 387(387) = 9 * 43 (both primes , end of excercise)factorize 390:(390) = 2 * (195) = 3 * (65) = 5 * 13 (both primes , end of excercise)
How do you prime factorize 15?
3 times 5
If you prime factorize a number and you use the ladder method why do you always have to divide by prime numbers?
It's more efficient. You want to end up with all prime numbers. You could divide by a composite number, but you'd just have to break that number down later. It saves steps.

What is the prime factorization of 74?
Prime factor means the factors of the number which divides the number. Example :- 15= 3× 5 . Here the 3 and 5 are the prime factors of 15. Prime factors of 74 - 2×37.
What is factorise in maths?
When you factor a number, you break it down into factors that multiply up to the number. For example, 12=3x4. There is also prime factorize when you factor the number into primes. For example, 100=2^2x5^2.
What is the highest prime factor of 420?
To find the highest prime factor of 420, we first need to factorize 420 into its prime factors. 420 can be expressed as 2^2 * 3 * 5 * 7. The highest prime factor is 7. Prime factors are numbers that can only be divided by 1 and themselves without leaving a remainder, and the highest prime factor is the largest prime number that can divide the original number.
