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 prime factorise 20 and give your answer in subscript form?
Factor out each prime by prime to obtain: 4 x 5 = 2 x 2 x 5 So the answer is 2² x 5 * * * * * and the word is "superscript", not subscript.
How do you find the largest cube factor of a number?
The answer depends on how good you are.You can either factorise the number completely and express it in terms of the exponents of its prime factors. Any prime with an exponent of 3 (or a multiple of 3) is a cube factor.A faster, but more demanding way is to see if 8, 27, 64 ... are factors.The answer depends on how good you are.You can either factorise the number completely and express it in terms of the exponents of its prime factors.

Can you factorise numbers on a scientific calculator?
Up till now you can't but hopefully will be able to do so soon.
How do you factorise 15x-27xy?
Factorising 15x-27xy gives 3x (5 - 9y).Factorising is to express a number or expression as a product of factors.When factorising always look for common factors. To factorise (15x-27xy) look for the highest factor between the two terms (3x). 15x - 27y = 3x (5 - 9y)
Is 33 prime or not prime?
