Prime Factors of 77

Steps to find Prime Factors of 77 by Division Method

To find the primefactors of 77 using the division method, follow these steps:

• Step 1. Start dividing 77 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
• Step 2. After finding the smallest prime factor of the number 77, which is 7. Divide 77 by 7 to obtain the quotient (11).
  77 ÷ 7 = 11
• Step 3. Repeat step 1 with the obtained quotient (11).
  11 ÷ 11 = 1

So, the prime factorization of 77 is, 77 = 7 x 11.

So, the prime factorization of 77 is, 77 = 7 x 11.

How do you define Prime Factors of a number?

Prime numbers, in mathematics are all those natural numbers greater than 1 that have exactly 2 factors which are 1 and the number itself. When we express any number as the product of these prime numbers than these prime numbers become prime factors of that number. Eg- Prime Factors of 77 are 7 x 11.

Properties of Prime Factors

• Prime factors are the set of factors that are unique to the number given.
• 2 is the only even prime factor any number can have.
• Two prime factors are always coprime to each other.
• 1 is neither a prime number nor a composite number and also 1 is the factor of every given number. So, 1 is the factor of 77 but not a prime factor of 77.
