2 x 3 x 3 x 3 x 5 = 270
As a product of its prime factors: 2*3*3*3*5 = 270
1,270,2,135
This is the factor tree of 270: 270 / \ 3 90 / \ 3 30 / \ 3 10 / \ 2 5 The 3's, 2, 5 would be prime so you would circle them.
write the number 14as a product of prime factor?
write the prime factorization of 625
The purpose of a factor tree is to notate the process of finding the prime factorization. If a number is already prime, a factor tree is not necessary.
Adv. as long as you try all primes starting with the smallest you will get the correct answer. Disadv. Time consuming. If you factor using larger numbers you can work faster, but you must remember to factor those as well. Ex Write the prime factorization of 270. You can easily see that 10 x 27 = 270 but neither is prime. Now factor both 10 and 27. 10 = 2 x 5 both are prime 27 = 3x9 but 9 is not prime so 27 = 3x3x3 all are prime So the prime factorization is 2x5x3x3x3 Faster if you just think and don't have to type it all to explain.
The answer is 2 and 19 since there both prime.
The answer is 2 to the third power.
Since 45 is a factor of 270, it is automatically the GCF.
a factor tree
The prime factors of 270 are the prime numbers that multiply together to give the original number. To find the prime factors of 270, you can start by dividing it by the smallest prime number, which is 2. 270 ÷ 2 = 135. Then, continue dividing by prime numbers until you cannot divide anymore. The prime factors of 270 are 2, 3, 3, 3, and 5, which can be expressed as 2 x 3 x 3 x 3 x 5.
