As a product of its prime factors: 2*3*7 = 42
Who to get the prime factorization of 19?
Let ask you this.....what factors make up the number 19 when you multiply? Is there any? Now figure out what your answer is.
Are prime factors and prime factorization the same?
No. Prime factors are the numbers that make up other numbers, but they have to be prime. Prime factorisation is the process of finding the prime numbers that create a number. This is when you multiply the prime numbers together and the product is the original number. For example: 20 5x4 5x2x2 This process is called prime factorisation. In this case, the prime numbers are 2, 2, and 5.
What factors add up to 240 that add up to 140?
Factors multiply. The same set of numbers won't add up to both 140 and 240, but 120 and 20 are factors of 240 that total 140.
What 2 numbers do you multiply to get 4095?
8190
What is HCF of 8 and 64?
To do this you first need to split the numbers up into their prime factors: 8 = 2x2x2 64 = 2x2x2x2x2x2 The next step is to identify any common prime factors. In this case both numbers have three 2s as prime factors. Multiply these together: 2x2x2 = 8 Thus the HCF of 8 and 64 is 8.
Why are prime numbers prime?
A prime number is any number that only has one and itself as factors. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
How is 4 the HCF of 28 and 60?
To figure out the HCF of 28 and 60, split them up into their prime factors: 28 = 2x2x7 60 = 2x2x3x5 The next step is to identify any common prime factors. In this case, both numbers have two 2s as prime factors. Multiply these together and you get: 2x2 = 4 Therefore 4 is the HCF of 28 and 60.
When you multiply two prime numbers you always get answer with prime number?
No. If you multiply any numbers, those numbers are factors of whatever product you get. Therefore, this product is a composite number; it has atleast the two factors you multiplyed before. Compposite numbers are never prime. If the two factors above were prime, you would still end up with a composite number. For example: 3 times 5 equals 15. The factors of 15 are 1, 3, 5, and 15. 15 is composite. 7 time 51 equals 357. The factors of 357 are 1, 7, 51, and 357. 357 is composite.
What prime numbers multiply up to 252?
2x2x3x3x7=252
What are the factors and prime factors of 72 that equal 19?
the prime factors of 72 are 2 and 3 6,12, and 1 (also factors) sum up to 19
Does any whole number multiply to get 29?
29 is a prime number, meaning it has no smaller factors. For any number up to 120, to check whether it is prime or not, it is sufficient to check whether it is divisible by the first four prime numbers (2, 3, 5 and 7).
