You don't find the prime factorization by using exponents, they're just a shorthand for notation once you find it. The prime factorization of 900 is 22 x 32 x 52

0 Look at the product of the first 3 prime numbers: 2 x 3 x 5 = 30. Any number multiplied by 30 will have a 0 in the units digit. So, no matter how many prime numbers you are multiplying, if once you have a number ending in 0, all of the rest will end in 0.

A factor tree is very useful when identifying the prime factors of a number. You draw two lines off of it and write two numbers that multiply together to make that number. If one of the numbers cannot be divided any further, then circle it. That is a prime number. Draw two lines off of numbers that can be divided further, so you have multiple branches dividing off into certain numbers. Once all the numbers have been divided down, you are left with prime numbers which you can then multiply to get back to the original number.

The GCF and the LCM of 20 and 36 are 4 and 180, respectively.To calculate the GCF of a series of numbers, you need to first figure out the prime factors of each of the numbers.The prime factors of 20 are 2, 2, and 5The prime factors of 36 are 2, 2, 3, and 3The two numbers share 2 and 2 as prime factors so the GCF = 2 x 2 = 4To calculate the Least Common Multiple (LCM), you need to first figure out the prime factors of each of the numbers, and then create a number using all the factors (but only using shared factors once).In this instance the factors required are 2, 2, 3, 3, and 5These, when multiplied together, give an product of 180

== == Yes. Once we open the field from integers to composite numbers, the gloves come off and lots of things are possible. Example: 1 1/2 = 3 x 1/3. The factor 3 is prime. All composite numbers have prime numbers as factors. Examples: 4 is a composite number of 2 x 2. 38 is a composite number of 2 x 19. 66 is a composite number of 2 x 3 x 11. == ==

A sudoku box cannot contain 5 prime numbers, so it is obviously an error. And once you accept that the numbers in the box are simply nonsense numbers, anything is possible.

There are none.Any number made by using the digits 0 to 9 once is divisible by 9 and so not a prime.There are none.Any number made by using the digits 0 to 9 once is divisible by 9 and so not a prime.There are none.Any number made by using the digits 0 to 9 once is divisible by 9 and so not a prime.There are none.Any number made by using the digits 0 to 9 once is divisible by 9 and so not a prime.

Once your prime factorization is complete and you discover that there are no numbers in common, the GCF is one and the numbers are declared to be relatively prime.

You need at least two numbers to find a GCF. The prime factorization of 99 is 3 x 3 x 11. Once you have the other one, you can compare.
