27 has four factors: 1, 3, 9 and 27
54 only has eight factors. They are: 1, 2, 3, 6, 9, 18, 27, 54.
Prime factors of 27 are 33Prime factors of 30 are 2 x 3 x 5Prime factors of 12 are 22 x 3Prime factors of 8 are 23The LCM is the product of all the primes to their greatest power,so the LCM of 27, 30, 12, and 8 is 23 x 33 x 5 = 8 x 27 x 5 = 1,080
A prime number has exactly two distinct factors: 1 and itself.27 has factors 1, 3, 9 and 27 - not prime8 has factors 1, 2, 4, 8 - not prime4 has factors 1, 2, and 4 - not prime11 has factors 1 and 11 - prime
8 only has four factors.
3.8 and 8 are factors.27 is their product.
The common factors of 24 and 27 are 1 and 3
8/27 is in simplest form since 27 does not go into 8. The easy way to write a fraction is simplest form is to write the numerator and the denominator in factored form, cancel out all the common prime factors and then multiply the what is left. So 8/27= 2x2x2/3x3x3 and we see there are no common prime factors so it is already in simplest form.

The first step in using primes for finding LCM is to find the factors of the given numbers. The LCM of the given numbers is the product of all the prime factors to their greatest power.An example of how use this method:Prime factors of 27 are 33Prime factors of 30 are 2 x 3 x 5Prime factors of 12 are 22 x 3Prime factors of 8 are 23The LCM of 27, 30, 12, and 8 is 23 x 33 x 5= 8 x 27 x 5 = 1,080
8: 2 12: 2, 3 27: 3 90: 2, 3, 5
The factors of 32 are: 1, 2, 4, 8, 16, 32. The factors of 81 are: 1, 3, 9, 27, 81.
The factors of 54 are 1, 2, 3, 6 9 18 27 54. The factors having a sum of 8 are 2 and 6.
