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 169 prime or not prime?
not prime
Maths. what is to factorise?
To factorise is to find the numbers that divide into the original number by only using prime numbers. For example factorise 20 = 2 times 2 times 5
Can you factorise every palindrome with odd number of digits?
No. 101 is prime.
How do prime factorise 9999 without repeating the digits?
It is: 32*11*101 = 9999
Factorise 693 by making use of prime factors only?
factorise 693 by making use of prime factors only The prime factors of 693 are 3, 7, 11 3*3 = 9 7*9 =63 11*63 = 693 See http://en.wikipedia.org/wiki/Sieve_of_Eratosthenes
Why the expression 5x-6y will not factorise?

How do you prime factorise 144 and write the answers in subscript form?
It is in exponents: 2^4 times 3^2 = 144

Does 63 have 6 factors?
Yes. You can find that out by adding one to the exponents of the prime factors and multiplying them. The prime factorization of 63 is 32 x 713 x 2 = 6
What is the difference between prime factorization and finding a factor?
A factor of a composite number need not be a prime number, some factors are themselves composite. Prime factorisation is continuing to factorise each factor unless it is a prime. For example, start with 30. 6 goes into 30 so finding a factor is satisfied by simply identifying 6 as a factor of 30. Now 30 = 5*6 where 5 is a prime, but 6 is not so we need to factorise 6. 6 = 2*3 and therefore, 30 = 5*2*3 = 2*3*5 The last is the prime factorisation of 30.
What is the factor that makes these prime numbers so important for the rsa?
It is very difficult to factorise a number that is the product of two very large primes but, given one of these primes, it is very easy to verify the result and to find the other prime.It is very difficult to factorise a number that is the product of two very large primes but, given one of these primes, it is very easy to verify the result and to find the other prime.It is very difficult to factorise a number that is the product of two very large primes but, given one of these primes, it is very easy to verify the result and to find the other prime.It is very difficult to factorise a number that is the product of two very large primes but, given one of these primes, it is very easy to verify the result and to find the other prime.
