Least common multiple of 15 25 and 30?
Prime factor each number. Use each prime factor the most it was used in any one number. 15=3x5 25=5x5 30=2x3x5 2x3x5x5=150
Are multiples of 5 prime or composite?
composite cuz 2x5=10 then 3x5=15 and it goes on
What is the LCM of 3X5 and 3X7 Using prime factorization?
The LCM of the given numbers is the product of all different prime factors to their greatest power. If there are no exponents, the greatest power of the prime factors is 1 and each different prime factor is used in the multiplication:prime factors of 15 are 3 x 5;prime factors of 21 are 3 x 7;the LCM of 15 and 21 is 3 x 5 x 7 = 105
What number can you multiply together to equal 15?
All of them. 1x15,2x7.5, 3x5, 4x3.75, 5x3...

what would 15 be as a product of prime?
3x5
Numbers with 4 Factors?
4 = 4, and 4 = 2 x 2, so either a single prime number to the power 4-1 (23, 33, etc.), or two different prime numbers, each to the power 2-1, for example, 2x3, 2x5, 3x5, etc.

What is the HCF of 15and 51?
To find this you first have to identify the prime factors of each number. In this case they are: 15 = 3x5 51 = 3x17 The next step is to identify any common prime factors. In this case both numbers have a 3 as a prime factor. Therefore the HCF of 15 and 51 is 3.
How many integers between 13 and 19 inclusive have an even number of prime factors?
