Factorization of prime factors within 100 All of them
Every number is divisible by 1 and itself
The number of students within 100 is the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the reasons: 4 = 2 * 2 * 2 * 26 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 11 45 = 3 * 3 * 5 46 = 2 * 23 48 = 2 * 2 * 2 * 3 49 = 7 * 7 50 = 2 * 5 * 5 51 = 3 * 17 52 = 2 * 2 * 13 54=2*3*3*3 55=5*11 56=2*2*2*7 57=3*19 58=2*29 60=2*2*15 62=2*31 63=3*3*7 64=2*2*2*2*2*2 65=5*13 66=2*3*11 68=2*2*17 69=3*23 70=2*5*7 72=2*2*2*3*3 74=2*37 75=3*5*5 76=2*2*19 77=7*11 78=2*3*13 80=2*2*2*2*5 81=3*3*3*3 82=2*41 84=2*2*3*7 85=5*17 86=2*43 87=3*29 88=2*2*2*11 90=3*3*2*5 91=7*13 92=2*2*23 93=3*31 94=2*47 95=5*19 96=2*2*2*2*2*3 98=2*7*7 99=3*3*11
Finally input finished, there should be no leakage
A composite number () is called the factorization prime factor
Fill in the blanks
A composite number (expressed in the form of multiplication of prime factors) is called decomposing prime factors
How to decompose a composite number into prime factors?
How to decompose a composite number into prime factors
Use short division to decompose prime factor. Prime number 2, 3 or 5 can be used to try division, but "1" can't be used to try division, because 1 is not prime number and composite number can't be used to try division. Because decomposing prime factor is to write a composite number into the form of multiplication of several prime numbers
At the same time, pay attention to the writing format. For example: 24 = 2 × 2 × 2 × 3 cannot be written as 2 × 2 × 2 × 3 = 24
