What is the HCF of 27 and 45?
To figure this out you should first express the numbers as the product of their prime factors: 27 = 3x3x3 45 = 3x3x5 The next step is to identify any common prime factors. Both numbers have two 3s as prime factors. Multiply these together and you get: 3x3 = 9 Thus 9 is the HCF of 27 and 45.
What is the HCF of18 and 54?
To find this, you first have to split the numbers into their prime factors: 18 = 2x3x3 54 = 2x3x3x3 The next step is to identify any common prime factors. In this case both numbers have a 2 and two 3s as prime factors. Multiply these together gives you: 2x3x3 = 18 Therefore the HCF of 18 and 54 is 18.
What is the HCF of 72 and 27?
To work this out, you first need to break the numbers down into their prime factors. This gives: 72 = 2x2x2x3x3 27 = 3x3x3 The next step is to identify any common prime factors. In this case both numbers have two 3s as prime factors. Multiply these together and you get: 3x3 = 9 Therefore the HCF of 72 and 27 is 9.
Which of the following is one of the two binomial factors of 6s2 40s - 64?
it is 3s - 4
What is one of the two binomial factors of 6s exp 2 40s - 64?
3s-4
What is the greatest common factore of 18 and 45?
The GCF of 18 and 45 is 9.The prime factors of 18 are 2, 3 and 3The prime factors of 45 are 3, 3 and 5Only the two 3s are common to both numbers, so the highest common factor will be 3 x 3 = 9It is 9The GCF of 18 and 45 is 9. The common factors of both numbers are 1, 4, and 9.
What is the LMC 54 and 63?
To find the LCM of two numbers, you need to first write them as their prime factors. In this case, 54 and 63 split to: 54 = 2x3x3x3 63 = 3x3x7 The next step is to identify any common factors. In this case, both numbers have two 3s as factors. Thus we can discard two of them. That leaves us with 2, 3, 3, 3 and 7. Multiply these factors together to get the LCM: 2x3x3x3x7 = 378. Thus the LCM of 54 and 63 is 378.
What is the LCM of 36 17 and 35?
To find the LCM of three numbers you first have to break them down into their prime factors. In this case: 27 = 3x3x3 18 = 2x3x3 10 = 2x5 The next step is to identify any duplicates and cross them out. In this case two numbers share two 3s as prime factors, and two numbers share a 2 as prime factor. That leaves us with 3, 3, 3, 2 and 5 as the prime factors to work with. Multiplying these together gives 270, and so the LCM of 27, 18 and 10 is 270.
Why is their different value for two 3s in 3.453?
Each two 3s have different values because they are in different postion
What is the HCF of 9 and 36?
The first thing you need to do to find the HCF is split each number into its prime factors. 9 = 3x3 36 = 3x3x4 Then you identify any shared factors. In this case, both numbers have two 3s, so those are our shared factors. Multiply these together for our answer: 3x3=9 Thus the HCF of 36 and 9 is 9.
What is the largest number less than 100 that is relatively prime to 170?
A number is relatively prime to a number if it has no common prime factors with that number. To calculate relative primes, we need to break 170 down into its prime factors. These are: 2, 5, 17. Thus we want to find a number that is made up solely from multiplying 3s, 7s, 11s, 13s, 19s, 23s, 29s and 31s together. The largest number less than 100 that meets this criteria is 99, which has prime factors of 3, 3 and 11.
What is the HCF of 45 and 36?
Oh honey, the Highest Common Factor (HCF) of 45 and 36 is 9. It's like finding the one friend who can handle both your drama and your jokes - they just click. So, 9 is the magic number that can divide both 45 and 36 without any leftovers.
