Prime factorization: It is a method to express each number as the product of prime numbers.Step 1: Which prime number divide 75?Ans: 3 and 5.But, we should start with the smallest prime number which divides 75.75÷3 = 25Step 2: Which prime number divide 25?Ans: 525÷5 = 5Step 3: We have to continuously divide each quotient by a prime number until the quotient itself is a prime number.In step 2 we are left with 5(prime number) as a quotient.So, prime factorization of 75 = product of all the quotients = 3x5x5
To express 160 as a product of prime factors, we can break it down step by step. First, 160 can be divided by 2, giving us 80. Continuing this process, we get: 80 = 2 × 40, 40 = 2 × 20, 20 = 2 × 10, and 10 = 2 × 5. Therefore, the prime factorization of 160 is (2^5 \times 5).
yes its 3x5x5

The prime factorization of 93 is 3 x 31. Draw it however you wish.

It is: 2*2*5*5 = 100
It is itself because 31 is a prime number
You can find the prime factorization of 130: 130 = 2*5*13 Therefore the answer is 1. Or you can skip a step. Just divide 130 by 2. You get 65, which is an odd number. Therefore there is only 1 factor of 2 in the factorization of 130.
Notice whether the number is odd or even. If it's even, the first prime factor is 2.
it is a way of finding out all of the prime numbers that you have to multiply to equal the desired number.
