As a product of its prime factors: 3*7*7 = 147
3 x 72
Prime Factorization "Prime Factorization" is finding which prime numbers you need to multiply together to get the original number. Example 1 What are the prime factors of 12? It is best to start working from the smallest prime number, which is 2, so let's check: 12 ÷ 2 = 6 But 6 is not a prime number, so we need to factor it further: 6 ÷ 2 = 3 And 3 is a prime number, so: 12 = 2 × 2 × 3 As you can see, every factor is a prime number, so the answer must be right - the prime factorization of 12 is 2 × 2 × 3, which can also be written as 22 × 3 Example 2 What is the prime factorization of 147? Can we divide 147 evenly by 2? No, so we should try the next prime number, 3: 147 ÷ 3 = 49 Then we try factoring 49, and find that 7 is the smallest prime number that works: 49 ÷ 7 = 7 And that is as far as we need to go, because all the factors are prime numbers. 147 = 3 × 7 × 7 = 3 × 72
No, 3x5x4 is not a prime factorization of 60. A prime factorization of 60 would consist of only prime numbers. The prime factorization of 60 is 2x2x3x5.
When all the factors are prime numbers, that's a prime factorization.
147=3x7x7
Prime factorization of 147 3*77 3x7x7
The prime factorization of 147 using exponents is 3 X 72.
the prime factorization would be 3*7*7
As a product of its prime factors: 3*7*7 = 147
It is: 3*7*7 = 147
31 x 72 = 147
147 = 3 x 7 x 7
3 x 7 x 7 = 147
147 = 3 x 7 x 7
3 x 72 = 147
