Both of these are acceptable for 640:
- 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5 = 640
- 27 x 5 = 640

How do you show the number 75 as a product of prime numbers?
3 x 5 x 5 = 75
How can you show your work on how to write 84 as the product of prime numbers?
2 x 2 x 3 x 7 = 84
How do you show a product of prime factors?
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.
Write a multiplication equation that has 3 numbers in it to show 64 as a product of prime numbers?
It will take six. 2 x 2 x 2 x 2 x 2 x 2 = 64
Show all prime numbers?
That's an infinite list.
What is it called when you show a composite number as a product or prime number?
Showing a composite number as a product of prime numbers is called prime factorization.
How do you show 24 as a prime number?
24 as a product of prime numbers is 2 x 2 x 2 x 3.
How do you show the number 75 as a product of prime numbers?
3 x 5 x 5 = 75
Can you show all the prime numbers?
Impossible. The number is infinite.
How do you show that there are no prime numbers from 200 - 210?
There are no prime numbers in that range.
How can you show your work on how to write 84 as the product of prime numbers?

What is the prime factorizations of 23?
23 is a prime number so there is no prime factorization. Some consider it to be acceptable to write 1 X 23 in order to show the number is prime, even though 1 is not a prime or composite number.23 is already prime.
Who created prime numbers?
The surviving records of the ancient Egyptians show that they had some knowledge of prime numbers
What are the prime numbers 1 to 250?
A prime number can only be multiplied by one or by itself.the best part about this is that the only even prime number is two...others are all odd numbers. What im trying to do is not just giving you the answer...but if I show you how to do it you could turn it into a two minute problem :D
Is the product of three irrational numbers always an irrational number?
No. The easiest counter-example to show that the product of two irrational numbers can be a rational number is that the product of √2 and √2 is 2. Likewise, the cube root of 2 is also an irrational number, but the product of 3√2, 3√2 and 3√2 is 2.
How do you prove that if the sum of two prime numbers is prime then one of the numbers is 2?
We know that a prime number is a positive integer greater than 1, whose divisors are 1 and itself. We know that the only even prime number is 2. That means that all other prime numbers are odd numbers.We know that when we add two odd numbers the result is an even number, which are not prime numbers (expect 2, and 2 = 1 + 1 where 1 is odd but is neither prime nor composite). Thus adding two odd prime numbers cannot give us another prime number. We show that the conclusion follows from the premise:Assume that r = p + q where all r, p and q are prime numbers, then we have that ris either even or not:* If r is even then r is at least 4 (the smallest number which is the sum of two primes) and thus not a prime number. This contradicts the assumption that r is a prime number, and therefore we conclude that r is not even. * If ris odd then either p or q must be odd and the other one must be even, since both p and q are prime numbers one of them must be 2 (the only even prime number). 2 + 3 = 5, 2 + 17 = 19, are examples of such numbers.
