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.

To work this out, you need to write the numbers as the product of their prime factors: 24 = 2x2x2x3 64 = 2x2x2x2x2x2 The next step is to identify any common prime factors. In this case both numbers have three 2s as prime factors. Multiply these together and you get: 2x2x2 = 8 Thus the HCF of 24 and 64 is 8.
The factors of 8 are 1, 2, 4, and 8 and their product is 64. There is no particular significance in the product of the factors of a number.
As a product of its prime factors: 2*2*2*2*2*2*2*2*5 = 1280 or as 2^8*5 = 1280
As a product of its prime factors: 2*2*2 = 8
Numbers that have 2 factors are prime numbers; Numbers that have 4 factors are either: * the cube of a prime; or * the product of two different primes; Numbers that have 8 factors are either: * a prime to the power 7; * the product of a prime cubed and different prime; * the product of three different primes.
2 x 2 x 2 = 8
8 and 5
The factors of 48 are: 1 2 3 4 6 8 12 16 24 48 The prime factors are: 2 x 2 x 2 x 2 x 3
2 x 2 x 2 = 8
1 x (2)8
It is: 2^8 times 5 = 1280
The factors of 168 are: 1 2 3 4 6 7 8 12 14 21 24 28 42 56 84 168 The prime factors are: 2 x 2 x 2 x 3 x 7
As a product of its prime factors: 2*2*2*2*2*2*2*2*5 = 1280 Or as: 2^8 times 5 = 1280
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, ....... The above numbers are known as prime numbers. What they have in common is that each of them have only two factors, the number itself and one. Numbers can be expressed as the product of their prime factors. For example the factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24 but only 2 and 3 are called prime factors because they are in fact prime numbers. So 24 expressed as the product of its prime factors is 2x2x2x3 or 23x3. The prime factors of 2310, which is MMCCCX in Roman numerals, are 2, 3, 5, 7 and 11. Therefore: MMCCCX expressed as the product of its prime factors is II*III*V*VII*XI. Note that number 1 is not considered to be a prime number because it has only one factor.
