Divide the number by each prime up to the prime that will go into the number leaving no remainder: 648/2=324 324/2=162 162/2=81 81/3=27 27/3=9 9/3=3 3/3=1 Listing each divisor as a prime factor, the prime factorization of 324 is 2x2x2x3x3x3x3 or 23x34.
To find the prime factorization of a number, divide the number by each prime number up to the greatest prime that will go into the number leaving no remainder.As an example, this is the process for factorization of 648:648/2=324324/2=162162/2=8181/3=2727/3=99/3=33/3=1Listing each divisor as a prime factor, the prime factorization of 648 is 2x2x3x3x3x3 (or 23x34 in exponential form).Keep dividing the original number by prime numbers until all the factors are prime. A large majority of the numbers you will encounter are multiples of 2, 3, 5 and/or 7. Start there.well first of all you need to know what prime factorization means: prime factorization is the process of decomposing a number into its constituent prime numbers; the calculation of all prime factors in a number. Step 1: write your number down and draw 2 diaganal lines down on each side no w you will need to find to factors that will multiply equally to get the number. say you had 10 the two numbers would be 2 * 5= 10, 2 is prime and 5 is prime so you cirle both of them and your prime factorization would be 10=2x5 and that is how you do prime factorization.
