How do you check if a large number is prime or a composite number?
You divide the number by 2. If the number is able to divide WITHOUT a remainder, then it is a prime number. If you divide a number by 1, you will get the same number. That is not a prime number.
Will you have a remainder if you divide an even number by a prime number?
Not always. 8 ÷ 2 = 4 14 ÷ 7 = 2
How can you tell that 187 is not a prime number?
A prime number is a number that is only evenly divisible by 1 and itself, since 11 and 17 both divide equally (no remainder) into 187 - it is not prime.
Is twenty-one a member of the prime number set?
A prime number is a number that only has two factors. That is, it can only divide evenly (without leaving a remainder) by 1 and itself. 21 can divide by 3 to give 7. Therefore it has more factors than just 1 and itself. Thus twenty-one is not a member of the prime number set.
What number can you divide by 5 and have 4 as the remainder?
24

Describe a way to find the prime factorization of any whole number?
Divide it by each prime number which does not have remainder.
Will you have a remainder if you divide an even number by a prime number?
Not always. 8 ÷ 2 = 4 14 ÷ 7 = 2
Prime factor of 9?
To find a prime factor of a number, divide by 2 and see if you get no remainder. Then divide by 3, 4, 5, and so on, until one of the numbers you try gets you no remainder. If no such numbers work below the number you chose, it is prime. In the case of the number 9, 2 does not go into 9, but 3 does.
How can you tell that 187 is not a prime number?
A prime number is a number that is only evenly divisible by 1 and itself, since 11 and 17 both divide equally (no remainder) into 187 - it is not prime.
Find the smallest number that meets all of these conditions divide the number by 5 remainder 3 divide the number by 8 remainder 2 divide the number by 9 remainder 4?

Suggest two different methods of knowing if a given integer is prime and analyze them?
With exception of '2' all prime numbers are odd. Any odd number that ends in '5' is not a prime. Any number that ends in 0,2,4,6,8 are even and not primes. '9' is a composite number and not a prime. So you are left with 3 or 7 , which are primes. So taking a number , say '23' divide by '3' leaves a remainder of '2' so it is a prime. Similarly '23' divided by '7' leaves a remainder of '2' so 23 is a prime. If No remainder is left then the number is composite and not a prime. e.g. 4567 is it a prime ? Its odd so could be a prime Does it divide by '3' answer 1522 remainder '1' so it is a prime. Try '7' answer 652 remainder '3' it is a prime. Hence 4567 is a definite prime number.
How do you make a remainder into a decimal?
you have to divide the remainder by the number you are dividing
What divides into 5?
Since 5 is a prime number only the numbers 1 and 5 divide it without a remainder.
What number do you divide by 7 and the remainder is 3?
When you divide 24 by 7 the remainder is 3.
What is the whole number remainder you can divide by 5?
Your question's meaning eludes me. You can divide any number by 5, whether or not it is a remainder, and why would you want to divide a remainder by 5 anyway?
