A factor is a number or algebraic expression by which another is exactly divisible. A multiple is a number that can be divided by another number without a remainder. A multiple factor is an oxymoron.
A prime number is both a factor of itself and also a multiple of itself.
A factor of any number is a multiple of that number as for example 3 is a factor of 24 and it is also a multiple of 3 because 3*8 = 24
No, that's just a factor. A common factor is when that factor is also a factor of another number.
Because 2 is a factor of 4. If a number is a multiple of four, when you add that it is a multiple of 2 there is no extra information, no additional factor.
They are common multiples.
28 is a factor of 28, as 28/28 = 1. 28 is also a multiple of 28, as 28*1 = 28.
There is no such number. If a multiple of 4 is a factor of 30, then 4 must also be a factor of 30, but 4 is not a factor of 30 (the factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30), thus no such number exists.
Divisor is just another name for factor.
