Why is it important to be able to write large numbers as factors of prime numbers?
All composite numbers can be expressed as the product of prime numbers. This is accomplished by dividing the original number by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 30 30 Divide by two. 15,2 Divide by three. 5,3,2 Stop. All the factors are prime. 2 x 3 x 5 = 30 That's the prime factorization of 30.
What whole number has a factor that is the greatest prime factor between 1 and 30?
It is: 29
What is the greatest common factor of 45 and 55?
The greatest common factor of 45 and 55 is 5 To determine GCF you first find the prime factors of each number. For 45 this is (5, 3, 3). For 55 this is (11, 5). Then you take the product of the prime factors that they have in common. In this case the only prime factor they have in common is 5 so the answer is just 5. For a better illustration of the rule look at 45 and 30. Prime factors of 45 are (5, 3, 3) Prime factors of 30 are (5, 3, 2) The prime factors in common are 5 and 3 and the product of these numbers is 15. Therefore the GCF of 45 and 30 is 15.
