The factors of a number are the whole numbers that can be divided by that number, and give a result that is also a whole number. For example, 4 is a factor of 12 because 12/4 = 3. 5 isn't a factor of 12 because 12/5 = 2.4, which isn't a whole number.
A Prime number is a number whose only factors are 1 and itself, for example 7. The only numbers that divide into 7 are 1 and 7, so it is prime.
Prime factorisation means finding all the factors of a number that are themselves prime, and then finding how many times you need to multiply each of them to get the original number.
All numbers have factors. These are numbers that multiply together to make the original number. Some of those factors are prime numbers. A number is prime if it only has two factors: one and the number itself.
In prime factorization, exponents are used to keep track of repeated factors.
The prime factorization of 72 is 2 x 2 x 2 x 3 x 3. In exponential form, that's 2^3 x 3^2
No. 30 isn't prime.
Yes, 2x3x5 is a prime factorization because it has prime numbers multiplied to give a number. It is the prime factorization of 30.
A prime factorization is a multiplication sentence of prime factors. 2, 3 and 5 are the prime factors of 30. 2 x 3 x 5 is the prime factorization of 30.
8 is not a prime factor of 30. The prime factorization of 30 is 2x3x5.
Prime factorization of 32 = 2x2x2x2x2 Prime factorization of 90 = 2x3x3x5 Prime factorization of 30 = 2x3x5 What is common in the prime factorization of the numbers? Only 2 is common, so GCF is 2.
30
2 x 3 x 5 = 302, 3, and 5
The factors of 30 are 1,2,3,5,6,10,15 and 30. The prime factorization of 30 is 2 x 3 x 5.
30 has the prime factorization 2 x 3 x 5
Not a lot of room between 29 and 30. Prime factorization is the expression of a positive composite integer as the product of its prime factors. 30 has three prime factors. 2 x 3 x 5 is the prime factorization of 30.
30 15,2 5,3,2
They are: 2*3*5 = 30
