The answer is 45 135=3x3x3x5 315=3x3x5x7 each number has at least 2 3s and one 5 3x3x5=45 Your welcome
What is the factors of numbers 45 and 42?
45=3x3x5. 42=2x3x7 1, 2, 3, 6, 7, 14, 21, 42 1, 3, 5, 9, 15, 45
What is the HCF of 60 and 45?
To find the HCF of two numbers you first need to express them as the product of their prime factors. In this case you'd get: 45 = 3x3x5 60 = 2x2x3x5 The next step is to identify any common prime factors. In this case both numbers have a 3 and a 5 as a prime factor. Multiplying these together gives: 3x5 = 15 And so 15 is the HCF of 45 and 60.
What is HCF and LCM of 30 and 45?
To find the HCF you first need to break the numbers down into their prime factors. In this case we have: 30 = 2x3x5 45 = 3x3x5 The next step is to identify any common factors. In this case both numbers have 3 and 5 as prime factors. To find the HCF, multiply these together: 3x5 = 15. To get the LCM, multiply the numbers together then divide by the HCF: 30x45/15 = 90.
Why is the prime factorization of 45 equals 3x3x5?
There are two ways to why the prime factorization for 45 equals 3x3x5. First of all, you may start with multiplying it. Start with 3x3; which equals nine or 9. Then 9x5 equals 45. the other way is that you may break it down, starting from 45. first you find 2 factors that you can multiply to receive the answer or product of 45. If you said 9x5 you are correct. So therefore you below the number 45 you may write the equation 9x5. Then you check if any of the numbers can be reduced or simplified. Let's start with the 5: can you find any factors of five? No, so you bring down the 5. How about 9? Yes, 3x3. Are there any others? No, there are no others, unless you include 9x1. But that's too easy. Below the 9 and beside the 5 write the multiplication sign, then 3x3. It should look something like this: 4 5 ^ 9 x 5 ^ ^ 3 x 3 x 5 sorry if the computer distorts the prime factorization tree.
