What scale factor is appropriate for reduction?
Any factor between 0 and 1.
Is zero is a factor of every positive number?
No, for 0 to be a factor, the numbers would have to be divisible by 0. You can't divide any number by 0, so it can't be a factor.1 is a factor of every positive number.
How do you find all the factors for a number without listing them all?
It is not simple. The only systematic way is to find the prime factorisation of the number and write it in exponential form. So suppose n = (p1^r1)*(p2^r2)*...*(pk^rk) where p1, p2, ... pk are prime numbers and rk are the indices (or powers). Then the factors of n are (p1^s1)*(p2^s2)*...*(pk^sk) where 0 ≤ sk ≤ rk. And remember that anything raised to the power 0 is 1. Example: n = 72 = 2*2*2*3*3 = (2^3)*(3^2) so, the factors of n are (2^a)*(3^b) where a = 0, 1, 2 or 3 and b = 0, 1 or 2. When (a, b) = (0, 0) the factor is 1. (a, b) = (1, 0) the factor is 2. (a, b) = (2, 0) the factor is 4. (a, b) = (3, 0) the factor is 8. (a, b) = (0, 1) the factor is 3. (a, b) = (1, 1) the factor is 6. (a, b) = (2, 1) the factor is 12. (a, b) = (3, 1) the factor is 24. (a, b) = (0, 2) the factor is 9. (a, b) = (1, 2) the factor is 18. (a, b) = (2, 2) the factor is 36. (a, b) = (3, 2) the factor is 72.
Is 1 a factor of every whole number?
No. Apart from -1 and 1, no other whole number is a factor of 1.
What are the factor pairs of 0 and 1?
Since zero has infinitely many factors, it can be said that any pair of numbers (0,n) - where n is an integer - are a factor pair for zero.1 = 1 * 1
