Yes, by definition a factor divides a number exactly

Work your way through the prime number posibilities. It's odd so there are no even factors. Add all the digits together (to get 12) and the result has a factor of 3 so 561 has a factor 3. Divide by that factor 3 to get 187. Try again for another factor 3 and there isn't one. The number 187 doesn't end in 5 (or 0) so 5 is not a factor. 7 doesn't divide exactly. 9 doesn't divide exactly. 11 does, so it is a factor. Divide by 11 to get 17 which is a prime number, so that's the finish. The factorization is 3x11x17
The smallest positive integer that will divide exactly into all the numbers in any set of numbers is 1. The largest integer that will divide exactly into 567 and 8 is also 1 - this is their Highest Common Factor. The smallest integer that 567 and 8 will both divide into is 4536 - this is their Lowest Common Multiple.
is a 'factor' of the second number.
Factors come in pairs. If you know one factor, divide it into the number. The answer will be another factor.
divide the number by 4, 6 , or 8 and if it come out to be a whole number it is a factor of it.
