Factors are numbers or algebraic expressions by which another is exactly divisible.
Divisibility is the state of being capable of being divided by another number without a remainder: 24 is divisible by 4.
Factors go into numbers, numbers go into multiples. Divisibility shows what factors come out of what multiples.
No!
Factors of numbers are divisible by them with no remainders
It is divisible by any of its factors including itself
Its factors are: 1, 3, 71 and 213
Divisibility rules help you find the factors of a number. Once you've found the factors for two or more numbers, you can find what they have in common. Take 231 and 321. If you know the divisibility rules, you know that they are both divisible by 3, so 3 is a common factor.
