How do you find the prime factorization of 900 using exponents?
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
What is the units digit of the product of the first 100 prime numbers?
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.
What is a diagram used to identify the prime factors of a number?
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.
What are the greatest common factor and least common multiple of 20 and 36?
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
Can composite numbers have prime numbers as factors?
== == 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. == ==
How many 9 digit numbers using 1-9 once are prime?
None.
What are five primes numbers using 0-9 only once?
2,5,13,647,809
How can a sudoku box with five prime numbers not contain 941?
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.
What are 5 prime numbers using the numbers 09each once?
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.
How can you use prime factorization to determine if two numbers are relatively 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.
How many five digit numbers can be formed using the numbers 1-60 only using each number once in each combination?
61
Find th greatest common factor of the numbers using prime factorization of 99?
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.
Do you really know all the prime numbers?
The way to know the Prime Numbers is to find out if they can only Multiplied Once ,The way to know Composite Numbers is to find out if they can be Multiplied Twice
How many five-digit numbers can be created using the digits 0-9?
9
Only once in American history has there been a decade in which four of the years were prime numbers can you find it?
The 1870s. 1871, 1873, 1877, and 1879 are all prime numbers.
What is the mean of all the positive five digit numbers that can be formed by using each of the digits 1 2 3 4 and 5 only once in a number?
3
How many times can you multiply 3 prime numbers together to get 50?
Only once - thanks to the unique prime factorisation theorem.
