What are all the prime factors of 42?
Prime factors of 42 are 1, 2, 3, and 7. Factors of 60 are the numbers which divide 60 exactly without any remainder.
How do you decompose a prime factor?
Here’s how:
- Find two numbers that multiply to equal the original number; write them as numbers that branch off the original one.
- If either number is prime, circle it and end that branch.
- Continue branching off non-prime numbers into two factors; whenever a branch reaches a prime number, circle it and close the branch.
What is the prime factor decomposition of 40?

What are prime factors of a number?
A prime number is a counting number that only has two factors, itself and one. Counting numbers which have more than two factors (such as 6, whose factors are 1, 2, 3, and 6), are said to be composite numbers. The number 1 only has one factor and usually isn’t considered either prime or composite.
Is 42 prime or composite?
composite number
Yes, since 42 has more than two factors i.e. 1, 2, 3, 6, 7, 14, 21, 42. In other words, 42 is a composite number because 42 has more than 2 factors.
What does it mean to decompose a factor?
Decomposing a Factor (number) means to break apart the number to uncover the numbers within the factor. 7 = 5 + 2. 7 = 3 + 3 +1. 9 = 5 + 4. 9 = 3 + 3 + 3.
What is the prime factorization of 43?
Factors of 43 by Prime Factorization We just learned that 43 is a prime number. It has only 2 factors, 1 and the number itself. So the prime factorization of the number 43 is written as the number 43 (itself).
What is the prime factor of 45?
3 × 3 × 5
So, the prime factorization of 45 is 3 × 3 × 5 or 32 × 5, where 3 and 5 are the prime numbers.
What is the prime factor decomposition of 45?
1 × 3 × 3 × 5
A prime number that is not a composite number is a prime factor. Prime factorization of 45 = 1 × 3 × 3 × 5.
What are prime factors of 24?
Its pair factors are (1, 24), (2, 12), (3, 8), and (4, 6). The prime factorisation of 24 gives 2 x 2 x 2 x 3 = 23 x 3, where 2 and 3 are the prime factors of 24.
What prime factor means?
What are Factors and Prime Factors? Factors: The numbers which are multiplied to get another number. For example, 3 and 5 are the factors of 15, i.e. 3 × 5 = 15. Prime Factors: A factor which is a prime number and not a composite number is a prime factor. For example, 2, 3 and 5 are the prime factors of 30.
What is prime factor form?
Prime factorization is the way of writing a number as the multiple of their prime factors. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, and so on. The prime factorization of 72, 36, and 45 are shown below. Prime factorization of 72 = 23 × 32. Prime factorization of 36 = 22 × 32.
