When does a number have only two factors?
Prime Numbers. If a number has only two different factors, 1 and itself, then the number is said to be a prime number. For example, 31 = 1 31. 31 is a prime number since it has only two different factors.
How to find the highest factor of two numbers?
To find the highest common factorof two (or more) numbers, make prime factorsof the numbers and identify the common prime factors. Then the highest common factor is the product of the common prime factors. Example 4 Find the highest common factor of 60 and 150. Solution: The prime factorisation of 60 is: The prime factorisation of 150 is: Note:
Is there a perfect number that equals the sum of its factors?
6 is a number that equals the sum of its factors: 1 + 2 + 3 equal 6. Numbers like 6 that equal the sum of their factors are called perfect numbers. 6 is the first perfect number . 4 is not a perfect number because the sum of its factors (besides 4 itself), 1+2, is less than 4. Numbers like 4 are known as deficient numbers .
Which is the first perfect number in math?
6 is a number that equals the sum of its factors: 1 + 2 + 3 equal 6. Numbers like 6 that equal the sum of their factors are called perfect numbers. 6 is the first perfect number .
