Best Answer

If you multiply two different prime numbers together, you will have a number with four factors, because it will have those two numbers as factors, as well as 1 and itself.

Examples:

3 x 5 = 15 which has the factors 1, 3, 5, and 15.

2 x 11 = 22 which has the factors 1, 2, 11, and 22.

5 x 19 = 95 which has the factors 1, 5, 19, and 95.

1, 2, 4 Method(s) used: # The method is to find all of the factors of each, and then select the numbers that appear in each list. # Another method to find the common factors of numbers is to find the prime factorizations of each one, select all matching prime factors, and then combine them.

Answer:The common factors of 16 and 28 are 1, 2, and 4.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common.Methods:One way to determine the common factors is to find all the factors of the numbers and compare them.The factors of 16 are 1, 2, 4, 8, and 16.The factors of 28 are 1, 2, 4, 7, 14, and 28.The common factors are 1, 2, and 4.

The common factors of 4, 20, and 24 are 1, 2, and 4 First find the factors that go into the numbers The factors of 4 are 1, 2, and 4 The factors of 20 are 1, 2, 4, 5, 10, and 20 The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24 Then find the factors that match: The common factors are: 1, 2, 4.

All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors.

All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. The factors of 12 are 1, 2, 3, 4, 6, 12 Since 4, 6 and 12 are composite numbers, they are the composite factors of 12.

To find the GCF of two numbers you first need to split them both into their prime factors. For 52 and 4 these are: 52 = 2x2x13 4 = 2x2 The next step is to identify any common factors. In this case, both numbers have two 2s as factors. To find the GCF you take these common prime factors and multiply them: 2x2=4. Thus the GCF of 52 and 4 is 4.

The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36

You need at least two numbers to find a GCF.

No, this will find a common multiple, but not always the least. For example, 2 and 4 have a least common multiple of 4 but if you multiply them you get 8. In fact, the LCM will only be the product of two numbers if the numbers have no common factors. We call numbers with no common factors relatively prime.
