Answer» 45 = (9)(5)= (3)(3)(5) is the prime factorization of 45 since 3 and 5 are both prime numbers, and therefore, each cannot be "broken down" or factored any further.Three (3) and 5 are prime numbers because each is a positive integer that is exactly divisible (a zero remainder) by exactly two positive integers: itself and 1, i.e., 3/3 = 1 and 3/1 = 3; Also, 5/5 = 1 and 5/1 = 5.45 = 9 x 5= 3×3×5 done. 3 and 5 are prime |
