That means if you multiply 3 and m together, you will get the number. Suppose the number is 24. Then you know that m = 8.

If 21 divides into M what else must dive into M?

If 21 divides into M then all the factors of 21 must divide into M.The factors of 21 are 1, 3, 7, 21 (we usually avoid the factor 1 and the number)So, 3 and 7 must divide into M.

Is 1881 prime or composite?

Composite, 1881 divided by 3 equals 627.1881 is divisible by 9 as well. You can determine this by adding up the digits:1 + 8 + 8 + 1 = 18 (which is divisible by 9, so the original number is divisible by 9).This trick works to determine if a number is divisible by 3 as well (if the sum of digits is divisible by 3, then the number is divisible by 3).Since 1881 has factors of 1881, 1, 9 and (1881 / 9 = 209) and you can stop there; you have determined that the number is not prime. {By the way, 11 & 19 are also factors}Every number has factors of itself and 1. If it has other factors beside that, then it is composite. If those are the only 2 factors, then the number is prime.If a number X is divisible by another number M, then M is a factor of X.

Assuming the missing symbols are pluses, that factors to 3(m + 3)(m + 7)


How do you factor whole numbers into prime numbers?

For the most part, it's done by intuition. You can easily see the first few numbers. For instance, if it's an even number, one of the prime factors must be 2 (usually the easiest number). Then when the number is an odd number, move on to 3, then 5...etc. you will rarely come across numbers which have high prime factors. You can utilize some divisibility tests to save time.... Note: m|n = "m divides n" 2|m if m ends is even. <br /> 3|m if the sum of the digits of m is divisible by 3 (999 = 9+9+9 = 27, divisible by 3)<br /> etc... a more complete table: http://en.wikipedia.org/wiki/Divisibility_rule

Can you write a number that is divisible by 6 and not 3?

Impossible: if a number N is divisible by 6 then it exists a number M such as N = 6 x M then N = 2 x 3 x M, then N is divisible by 3
