No, 247 is NOT a prime number. The simple definition of a prime number in simple math is: Any number that can only be divided by itself and the number "1", the number is then PRIME, not composite. 247 is a composite number; its factors are: 1, 13, 19, 247.
Good question, I had to think on that a bit. Four ninths is greater than three sevenths.
The factors for the number 63 are 1, 3, 7, 9, 21, and 63.
2.47 = 247/100
60% of 63 = 0.60 * 63 = 37.8

247 is not prime. 247 = 13 * 19
Any number multiplied by 247.
63
Divide 247 by 2, if you get a zero remainder then 247 is an even number, otherwise it is an odd number, try it. Good luck!

I don't know how to "grate" a number ... numbers are not cheese. An infinite number of numbers are "greater" (larger) than 64. Likewise, an infinite number of numbers are not "greater" (in other words, less than) 64, starting with 63, 62, 61, ... Actually, there are an infinite numbers that are less than 64, but greater than 63, unless you specify "whole numbers".
36 is -27 greater than 63.
1, 13, 19, 247.
63 + 30% = 63*1.3 = 81.9
247 is a composite number because it has more than two factors
