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.

To find the square numbers that are factors of 1600, we first need to find the prime factorization of 1600, which is 2^6 * 5^2. A square number is a number that can be expressed as the square of an integer. In this case, the factors of 1600 that are square numbers are 1, 4, 16, 25, 64, 100, and 400. Therefore, there are 7 square numbers that are factors of 1600.
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.
