Find a factor tree for each of the following numbers. a. 36 b. 54 c. 102 d. 1000 A factor tree is not the only way to find the prime factorization of a composite number. Another method is to divide the number first by 2 if possible, then divide the quotient by 2 if possible, then by 3, then by 5, and so on, until all possible divisions by prime numbers have been performed. For example, to find the prime factorization of 108, you might organize your work as follows to conclude that 108 = 2^2 times 3%^3. Use this method to find the prime factorization of the following numbers. a. 216 b. 2940 c. 825 d. 198, 198
