30 and 60
64, 729, 15625 and so on. Prime numbers to the 6th power.
The two numbers that have 105 as their least common multiple (LCM) are 15 and 7. This is because the LCM of two numbers is the smallest number that is a multiple of both numbers. In this case, 15 and 7 are both factors of 105, and no smaller number can be a multiple of both 15 and 7.
Both 10 and 20 are two-digit numbers that are factors of 20.
All numbers that have exactly two factors are prime numbers whereas composite numbers have more than two factors.
Factor both numbers. Select the factors they both have in common. Choose the largest (greatest) one.
49 and 98, among others.
10 and 20, among others.
They are called common factors when they are the same for two or more numbers. They are factors that are common to both number.
There are not any numbers that are both prime and composite. A prime number has exactly two factors. A composite number has more than two factors.
4 and 12 are two of them
30 and 60, among others.
30 and 60, among others.
No because they are both composite numbers having more than two factors whereas prime numbers have only two factors
All nonzero numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. Pick two numbers. Write down their factors. The numbers that appear on both lists are common factors.
