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.

the probability for any side coming up is 1/6 How many ways can you get a Prime number? 1,2,3,5 How many results can you throw: 1,2,3,4,5,6 Pr(prime)=4ways/6possibilies=2/3

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 ...

Prime factors of 32? 2 to some power. Try 2x2x2x2x2 or 2^5 81 is 9x9, so it must be in prime 3x3x3x3 or 3^4

Start by finding the prime factorization of each. Then you can find which prime factors the two composite numbers have in common, which leads to the GCF.

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 ...
