121 = 112
Prime factorization helps to find the greatest common factor and the least common multiple which, in turn, help in the adding, subtracting and reducing of fractions.
The prime factorization of the number at the top
To find the prime factorization of a number, it helps to divide it by any obvious factors. In this case, 156 is even so we can divide by 2. Do this and we get 78, which is also even. Divide by 2 again and we get 39, which is divisible by 3. Do that and we get 13 which is prime. Thus the prime factorization of 156 is 2x2x3x13. If we want to use exponents this can be written as 22x3x13
what is the fatorization of 54
In finding the LCM or HCF of two or more numbers
You use a factor tree, for the 2 denominators. Yes that is correct the answer on the top but it says 2 denominators. This is the real correct way To do Prime Factorization in fractions first prime factorization the numerator and then the denominator. then put the prime factorization of the numerator on top and put the prime factorization of the denominator on the bottom like fractions.
i know this is a bad answer but really, no where. my father said when he was young he learned it and never EVER used it once in his whole life.
Probably not, unless you pursue a career in the sciences.
Saying "The" Instead of "A"The prime factorization is used instead of a prime factorization because there is only one correct prime factorization of any given number. Of course, that refers to composite numbers because prime numbers have no prime factorization.The use of the word "a" implies that more than one prime factorization is possible when it's not. The use of the word "the" signifies that only one prime factorization is possible, though there are various ways to arrive at it.

use a factor tree
The prime factorization of 560 is: 2, 5, and 7
Precisely.
If your numbers have no prime factors in common, they are relatively prime.
If the prime factorization contains a 5 and a 7, 35 is a factor.
