What is prime factor example?
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 are prime factors of 18?
So, the prime factorization of 18 is 18= 2 × 3 × 3 . A factor tree is not unique for a given number. Instead of expressing 18 as 2 × 9, we can express 18 as 3 × 6.
How do you find a prime factor?
- Step 1: Divide the number by the smallest prime number such that the smallest prime number should divide the number completely.
- Step 2: Again, divide the quotient of step 1 by the smallest prime number.
Why is 11 not a prime number?

What is the prime factor of 80?
The number 80 is a composite number. The factors of 80 are 1, 2, 5, 10, 20, 40, and 80. A prime number does not have a factor other than 1 and itself. So, the prime factors of 80 are 2 and 5 .
What is the difference between prime factors and prime numbers?
The prime factorization of a number is the product of prime factors that make up that number. ... Factors are numbers that can be multiplied together to make another number . For example, 3 and 12 are a factor pair of 36. Prime numbers are numbers that have exactly two factors, 1 and itself (i.e. 2, 3, 5, 7, 11,....).
Is 1 a prime factor?
The number 1 is called a unit. It has no prime factors and is neither prime nor composite.
What is not a prime number?
Definition: A prime number is a whole number with exactly two integral divisors, 1 and itself. The number 1 is not a prime, since it has only one divisor. The number 4 is not prime, since it has three divisors ( 1 , 2 , and 4 ), and 6 is not prime, since it has four divisors ( 1 , 2 , 3 , and 6 ).
