the answer is 2,3,and5They are: 2, 3 and 521 2 3 5 Ans 2. 2 3 5. '''1 is not a prime number'''. (A prime is a number with '''exactly''' 2 factors. 1 has only one factor.)The prime factors of 30 are 2 x 3 x 5.

2 x 3 x 5 is the prime factorization of the composite number 30.

the Correct Prime Number To This Number indication Is 1 , 2 , 3 , &amp; 5 Thank You . The Solution

As a product of its prime factors: 2*2*2*5*5*5 = 1000 As a product of its prime factors: 2*2*3*5*5*5 = 1500

The prime factorization of a number is that number reduced down to a product of prime numbers. In this case, it is 2 x 2 x 3 x 3 x 3 x 5 x 5 x 5 x 5 x 5. To find out what number this is the prime factorization of, simply multiply it out: 337,500.

1x5 or 5x1 5 is already a prime number but two prime numbers that total up to 5 are 2+3=5.

The prime factorization of 30 is 2 * 3 * 5Start with the lowest prime number that will divide into the given number evenly.The result will be one of the prime factors and a number that might need to be factored. In the case of 30, 2 is a prime number and 15 needs to be factored further.The lowest number that will divide into 15 evenly is 3. 3 * 5 equals 15. 5 is also a prime number, so the prime factorization of 30 is 2 * 3 * 5.To find the prime factors of any number then divide the number by prime numbers of increasing value. When a prime number wholly divides the original number repeat the process with the same prime number but each time with the new quotient until complete division does not occur. Repeat with a prime number of higher value until the final quotient is 1.30 &divide; 2 = 1515 &divide; 2 complete division does not occur15 &divide; 3 = 55 &divide; 3 complete division does not occur5 &divide; 5 = 1 : quotient = 1, prime factorization is completeThe prime factors are therefore 2, 3 and 5.2 x 3 x 5 = 30

The prime factors of 30 are 2, 3, and 5. The prime factor of 31 is 31. The prime factors of 32 are 2, 2, 2, 2, and 2. The prime factors of 33 are 3 and 11. The prime factors of 34 are 2 and 17. The prime factors of 35 are 5 and 7. The prime factors of 36 are 2, 2, 3, and 3. The prime factor of 37 is 37. The prime factors of 38 are 2 and 19. So, the number must be 30, which is 2 x 3 x 5.

The easiest way to find all the factors of a number is to start dividing by the smallest prime number, 2. 150/2 = 75. Once you have done that, move up to the next prime number, 3. 75/3 = 25. Then the next prime number, 5. 25/5 =5 So, 150 = 2 * 3 * 5 * 5. Now that you have all the prime factors, you can find other factors by multiplying these numbers in all the combinations possible. i.e. 2 * 3, 2 * 3 * 5, 2 * 5, 2 * 5 * 5, 3 * 5, 3 * 5 * 5, 5 * 5
