Let's start by factoring out the obvious 50. 1050 = 50 * 21 The prime favors of 50 are 5*5*2 The prime factors of 21 are 3*7 The prime factors of 1050 are therefore 2*3*5*5*7 You could have done this problem other ways, but you'd get the same answer.

When the area is represented by a prime number e.g. area = 11 the sides can only be 1 by 11 area = 12 sides could be 1by12 or 2by6 or 3by4 so which are the prime numbers from 2 to 30? btw, 2 is considered a prime number.

2, 3 and 5 would be considered prime, which mean that 1, 4 and 6 are non-prime. The die has 6 sides. You should be able to work it out with that information.

You have to break 1260 down into it's number tree. Start by dividing the number by 2 until you can't do it evenly, then divide by 3, and so on until no more divisions can be made: 1260/2 = 630 So we have one prime factor, 2 and are left with 630: 630/2 = 315 Now we have two ...

**math**

A prime number is a positive integer that has exactly two positive integer factors, 1 and itself. For example, if we list the factors of 28, we have 1, 2, 4, 7, 14, and 28. That's six factors. If we list the factors of 29, we only have 1 and 29. That's two factors. So we say ...
