#### Steps to find Prime Factors of 178 by Division Method

To find the primefactors of 178 using the division method, follow these steps:

• Step 1. Start dividing 178 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 178, which is 2. Divide 178 by 2 to obtain the quotient (89).
178 ÷ 2 = 89
• Step 3. Repeat step 1 with the obtained quotient (89).
89 ÷ 89 = 1

So, the prime factorization of 178 is, 178 = 2 x 89.

#### Steps to find Prime Factors of 178 by Factor Tree Method

So, the prime factorization of 178 is, 178 = 2 x 89.

#### What does Prime factor in mathematics mean?

Prime numbers, in mathematics are all those whole numbers greater than 1 having exactly two divisors that is 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 178 are 2 x 89.

#### Properties of Prime Factors

• Two prime factors of a given number are always coprime to each other.
• 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 178 but not a prime factor of 178.
