30 is the first number that has factors of 2, 3, and 5.
30 and all multiples of 30 have 2, 3, and 5 among their factors.
A prime factor = prime number which can be divided into the given number with no remainder Prime factors of 150 are: 2, 3, and 5.
2 is a prime number. It is only evenly divisible by itself and one.3 is a prime number. It is only evenly divisible by itself and one.5 is a prime number. It is only evenly divisible by itself and one.
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
To find the number multiply 2 x 3 x 5. The answer is 30.
As a product of its prime factors 2*3*3*3*5*5 = 1350
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.
