How do you find coprimes of a number?
First, find the prime factorization of the number. For instance, with 45: 45 = 3 * 3 * 5 = 32 * 51 Now, from this prime factorization, any numbers whose prime factorizations do not include these factors is coprime to the number you have.
What number is 75?
The prime factorization of 75 is 3 x 5 x 5.
What number has 6 numbers in its prime factorization?
30030 has six prime numbers in its factorization (2x3x5x7x11x13).
What is the prime factorization in exponential form for the number 6?
2 x 3 = 6 You can put them all to the first power, but it's not necessary.
How can you choose one number so that it will be relativelyprime to any other number?
Find the GCF of the two numbers. If the GCF is 1, the numbers are relatively prime. or Look at the prime factorization of the first number. Choose a second number that doesn't have any prime factors in common with the first.
What is the lowest number that has a prime factorization made up of the first five prime numbers?
It is 2310.

What is the first step in finding the prime factorization?
Notice whether the number is odd or even. If it's even, the first prime factor is 2.
What number is 75?
The prime factorization of 75 is 3 x 5 x 5.
First prime number?
The first prime number is 2. If you're wondering why 1 is not prime, well, probably because you cannot break a number down if you divide it by 1. When it comes to prime factorization, if you bring 1 into it, the number you start with will stay the same (e.g., If you star a "prime factorization tree" for 100 and start off with 1, you will still have 100. You do not "grow" another "branch.")
What is the greatest common factor of 132 and 150?
The answer is 6.You need to do a prime factorization of the 2 numbers first. Then compare the 2 numbers and see what the greatest number they have in common is in the factorization of them. Next times what they have in common and there is your answer. The factorization of 132=11x3x2x2 The factorization of 150=5x5x3x2 There is a 2 and a 3 in each, so you multiply them both and you get 6.
What number has 6 numbers in its prime factorization?
30030 has six prime numbers in its factorization (2x3x5x7x11x13).
What is the prime factorization in exponential form for the number 6?
2 x 3 = 6 You can put them all to the first power, but it's not necessary.

What is the prime factorization of the number in the list which is a multiple of 7 48 72 126?
First, you have to find the number that is a multiple of 7. That number is 126 because 7 x 18 = 126. Then, you need to find the prime factorization. You can do that by starting with any factor pair of 126 and keep factoring the composite factors until all factors are prime. 126: 2 x 61 Since 2 and 61 are prime, that is the prime factorization of 126.
Prime factorization of 406?
406=2x203203=7x29PF=2x7x29The PF (Prime Factorization) of 406 is 2x7x29.*NOTE: When solving prime factorization, please use a factor tree. They're useful because when you start with a number, you find two factors that together multiplied equal the top number. If one of those factors are composite, find two factors for that number, and keep going until you come to a conclusion where the last number is prime. Therefore, the first factor for each composite factor of the top number, multiplied together, equal the number you started with.
How do you find the prime factorization of a square root?
Two ways: Find the square root first. If it's a whole number, find the prime factorization like you would for any other number. Or, find the prime factorization of the original number. The factors will be paired. Take one out of of each pair. Example: 900 The square root of 900 is 30. The prime factorization of 30 is 2 x 3 x 5 or The prime factorization of 900 is 2 x 2 x 3 x 3 x 5 x 5 The square root will be 2 x 3 x 5, or 30
