Yes. If a number is divisible by another number, that second number is a factor of the first. 6 is divisible by 2, 2 is a factor of 6.
Proper factors don't include one and the number itself.
They are two different words for the same thing.
no they cant they are not divisible by the same thing
Look at 12. Not divisible by 8 but divisible by 4 and 2. Look at 4. Same thing. The equation 8x-4 will give you any number divisible by 4 and 2, but not 8 32 is divisable by all three. 8x4=32, 2x16=32
yes they are because are used for the same thing as most things
They ARE the same.
The rule is: if a number is divisible by 5 and 17 at the same time, that number is divisible by 85
If a number is divisible by 4, it also means that the same number is divisible by 2. But if the number ends in a 3, it can't be divisible by 2 and, to a further extent, can't be divisible by 4.
The way I do it: first look at the number to see if there are any factors that can be recognized, such as 2, 3, 5, 9, 10. There are ways to recognize if a number is divisible by these numbers. If the number is divisible by any of those, then perform that division, and then check again (example there is no easy check for divisible by 27, but if you divide the number by 9, then the quotient will be divisible by 3). Keep track of what you're dividing by. Next you will just have to start testing dividing the number by primes: 7, 11, 13, 17, etc. Then, if you determined that you divided a number by 10, for example, the prime factors for 10 are 2 and 5. Do the same for 9 is prime factors of 3 and 3.
There is no number that is "divisible by 4" and "not divisible by 4" at the same time - a number cannot be both a multiple of 4 and not a multiple of 4.
no. a prime is only divisible by 1 and itself. a square number is two of of the same number multiplied together (5x5=25), giving it more than just two factors.
Some are, some are not. Binary is just a way of writing a number. It will still be divisible be the same numbers it was divisible by in base 10.
