What are the lowest numbers with 4 factors?
Six.
What makes this number special 2520?
It is the lowest number that has the first ten counting numbers as factors.
What factors of 25 and 4 are LCM?
All factors of 25 and 4 are lowest common multiples of some numbers. Factors of 25: 1, 5, 25 Factors of 4: 1, 2, 4 eg 25 is lcm of 5 and 25. The only (and thus) lowest common factor of 25 and 4 is 1. Thus the lowest common multiple of 25 and 4 is 100.
What is the lowest common multiple of 4 6 and 11?
To find the lowest common multiple of 4, 6 and 11 you first need to break these numbers down into their prime factors: 4 = 2x2 6 = 2x3 11 = 11 The next step is to identify any common factors. In this case two numbers have a 2 as a prime factor, so we can discard one of these. Take all the other prime factors (2, 2, 3 and 11) and multiply them together: 2x2x3x11 = 132. Thus the lowest common multiple of 4, 6 and 11 is 132.
Is 3 a prime or composite number why?
Prime numbers have exactly two factors. 3 has exactly two factors: 1 and 3. So 3 is prime. Composite numbers have more than two factors. 4 is composite because it has three factors: 1, 2, and 4.
What are the lowest numbers with 4 factors?
Six.
What is the lowest multiple of 4 and 6?
To work out the lowest common multiple of two or more numbers we need to resolve each number to its prime factors. Then, we can multiply those factors together to give us the lowest common multpile. The factors of 4 are 2, 2 The factors of 4 are 2, 3 To be a multiple of 4, the lowest common multiple must have 2 and 2 in its list to be a multiple of 4, the lowest common multiple must have 2 and 3 in its list So, starting with the 4 we have (2, 2) As there is already a 2 in the mix, when we come to the 6 we only need to add the 3 making our list (2, 2, 3) If we multiple all these numbers together we get 12. 4 x 3 = 12 6 x 2 = 12
What are numbers with only 3 factors called?
they are called numbers with 3 factors
What makes this number special 2520?
It is the lowest number that has the first ten counting numbers as factors.
What is the smallest numbers that have 3 factors?
4, with factors 1, 2 and 4
What factors of 25 and 4 are LCM?
All factors of 25 and 4 are lowest common multiples of some numbers. Factors of 25: 1, 5, 25 Factors of 4: 1, 2, 4 eg 25 is lcm of 5 and 25. The only (and thus) lowest common factor of 25 and 4 is 1. Thus the lowest common multiple of 25 and 4 is 100.
What is the fraction 16 20 in lowest terms?
Look for common factors in the two numbers. Divide both numbers by the common factors. Continue until there are no more common factors.
What numbers have 3 factors?
The squares of all prime numbers have 3 factors.
What numbers have factors does 3 4 5 have?
60 has those factors in common.
How are factors and multiples of a number are related?
Factors of the number will also be factors of the number's multiples. Multiples of the number will also be multiples of the number's factors.
How do you find the lowest multiple?
Assume we want to find the lowest multiple of the numbers. The lowest multiple of the numbers is factored to primes with the maximum exponents. The other way of thinking of the lowest multiple is that these numbers divide the large number in order for the large number to be the lowest multiple. To help us understand how to work out with lowest multiple, let's consider this following example: Find the GCF of 4 and 6. Factor out each term to obtain: 4 = 2 x 2 6 = 2 x 3 Select the maximum number of primes that occur the most in one of the numbers. It's 4 that contains the factors 2². Then, since 6 is the only number that contains 3, keep that! Then, the lowest multiple is 2² x 3 = 12.
What are 2 numbers that exactly have 3 factors?
4 (factors 1, 2 and 4) and 9 (factors 1, 3 and 9) are two examples.
