Prime factorization of 45 = 3x3x5Prime factorization of 60 = 2x2x3x5Prime factorization of 160 = 2x2x2x2x2x5Only common factors are 5 (and 1).Therefore GCF = 5.
Prime Factorization of 90To find the prime factorization of 90, start with the lowest prime number that will divide into 90. That number is 2. 2 times 45 equals 90. 2 is a number in the prime factorization of 90. Next, find the lowest prime number that will divide into 45. The number is 3, and 3 times15 equals 45. 3 is one of the prime factors, so now you have 2 times 3 times 15. 15 is not a prime number, and the lowest prime number that will divide into 15. 3 times 5 is 15. You'll notice that both 3 and 5 are prime numbers, so the prime factorization of 90 is 2 X 3 X 3 X 5. Check your answer to make sure it is correct and you're done.
32 x 5 = 45
The prime factorization of 45 is:3 X 3 X 5.Using exponents, it is written as:32 x 5.3^2 x 5
prime factorization of 4545 = 3 * 1515 = 3 * 5so prime factors are 3,3,5
3 x 3 x 5 = 45 In exponents: 32 x 5 = 45
3^2 x 5 = 45
It is: 32*51 = 45

how do i get the prime factorization of 45
Prime factorization of 45 is 3x3x5. Prime factorization of 65 is 5x13.
First, find the prime factorization of the number. For instance, with 45: 45 = 3 * 3 * 5 = 32 * 51 Now, from this prime factorization, any numbers whose prime factorizations do not include these factors is coprime to the number you have.
Students learn that the prime factorization of a number is the given number written as the product of its prime factors. For example, to find the prime factorization of 45, use a factor tree to find that 45 is 5 x 9, and 9 is 3 x 3. So the prime factorization of 45 is 5 x 3 x 3, or 5 x 3^2.
