How do you get the prime factorization of 90?
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.
Ronald writes the prime factorization of 90 as 2x3x3x5 on the board Donald write the prime factorization of 90 as 3²x5 Who is correct?
Ronald is correct, as 2x3x3x5 = 6x3x5 = 18x5 = 90. Ronald would have also been correct to put 2x32x5. Donald is incorrect, as 32x5 = 3x3x5 = 9x5 = 45.
