since its not a Prime number, there are a few.
a way to figure one out is if you add up all the digits and the sum is divisible by 3, then the entire original number is divisible by 3.
In this case:
3+1+5=9
9 is divisible bye 3 evenly, so 315 is divisible by 3. Now you have to figure out WHAT times 3 equals 315. the answer to this is 105.
315/21 = 15, hence 15 times 21 is 315
It is: 2 times 315 equals 630
5p2 = 315 Therefore, p2 = 315/5 p = sqrt(63) p = ±7.94
for multipcation!
Times to number by each other!
1x9:9 3x3:9
1 and 67
12.6 x 25 = 315
15 multiplied by 21 is 315.
39.375
500 minus 315 equals 185.
315/21 = 15, hence 15 times 21 is 315
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals". If the question is about 3a = 315, then a = 105.
It is the same as 315 divided by 7.5 equals 42
5 x 7 x 3 x 3 = 315
315/4 = 78 3/4 = 78.75
As a product of its prime factors: 3*3*5*7 = 315 or as 32*5*7 = 315
