What is the LCM of 38 20 and 28?
Factor out each number into primes to get: 38 = 2 * 19 20 = 2² * 5 28 = 2² * 7 Count the maximum number of distinct primes for all of these values. For instance, if 20 and 28 both have the maximum number of "2" 2, then write out 2². If one number has a prime factor while the rest of the number doesn't, then write out that prime factor. Following these steps, we have this product: 2² * 5 * 19 * 7 = 4 * 5 * 7 * 19 = 2660 So that is the LCM of the given numbers.
Is 28 a prime explain how?
No since it is an even number it has 2 as a factor. If the factors are the number itself and 1 it is prime. If there are more factors it is not. 28 has many more factors.28=22 x7So 2 and 4 and 7 are all factors as is 14.
What prime factors do 28 and 12 have in common?
Their only prime factor is 4.
What is the product of the prime factor 28?
I think you misworded your question. I am not exactly sure what you are looking for. If you want to know the prime factorization of the number 28, it is, 2^2 * 7. That is two squared times seven.
What is a factor firework to find prime factorization of 28?
7,2,2 14,2 28
