They are: 29*43 = 1247

Not a prime number as 5 divides in to it

The smallest prime number that divides 147 evenly is three (3).

383 is prime

Yes, 887 is a prime number. Recall that if a number is not prime then there exists a prime less than the square root of the number and this prime divides the number. So we need to check if the primes less than 30 divides 887 or not. These primes are 2,3,5,7,11,13,17,19,23,29.

to answer a prime number you must find a number that goes into it and that divides by itself :)

check if 2 divides the Numbercheck if 3 divides the Numbercheck if 5 divides the Number...check if any prime numbers less than the square root of the Number divide the NumberIf any do, the Number is composite; otherwise the Number is prime.This is called the Sieve of Erasthenes.An easy way to check if a prime number divides the Number in base ten (if you don't have a calculator) is to add or subtract 1 or 3 times the prime number to the Number, so that the sum or difference is a multiple of ten (if the prime number isn't 2 or 5). Knock off the zero. If the prime number divides the new number, it also divides the Number; otherwise it doesn't.
