How do you find positive factors?
To find the number of factors of a given number, express the number as a product of powers of prime numbers. Now, increment the power of each of the prime numbers by 1 and multiply the result. Therefore, there will 10 factors including 1 and 48. Excluding, these two numbers, you will have 10 – 2 = 8 factors.
What are the prime factors 72?
When a composite number is written as a product of all of its prime factors, we have the prime factorization of the number. For example, we can write the number 72 as a product of prime factors: 72 = 2 3 ⋅ 3 2 . The expression 2 3 ⋅ 3 2 is said to be the prime factorization of 72.
