How to Find the Prime Factors of a Number

A Prime Number can be divided evenly only by 1, or itself.  Example: 5 can only be divided evenly by 1 or 5, so it is a prime number. But 6 can be divided evenly by 1, 2, 3 and 6 so it is not a prime number (it is a composite number). A Composite Number can be divided evenly by numbers other than 1 or itself. Example: 9 can be divided evenly by 1, 3 and 9, so 9 is a composite number. But 7 can only be divided evenly by 1 and 7, so 7 is not a composite number (it is a Prime Number).  

If the integers p, p and p ¹ 0 dan p  ¹  1 only have 1 divider 1 and p, then p is called prime numbers. Integers other than primes are called composite numbers Examples of prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, ...etc. . Examples of composite numbers: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, ...etc.

A factor that is a prime number. One of the prime numbers that, when multiplied, give the original number.
Example:

The prime factors of 35 are 5 and 7 (5×7=35, and 5 and 7 are prime numbers).

Time Measurement Unit

As we all know, that the unit of time that there are various ranging from seconds, minutes, hours, days, weeks, months, years, and others. 1 hour = 60 minutes, 1 minute = 60 seconds to, 1 hour = 60 x 60 seconds = 3.600 seconds. 1 year = 12 months, 1 month = 30/31 days.

For example:
23 hours = ... minutes ?
23 hours = 23 x 60 minutes = 138 minutes.
43 minutes = ... second ?
43 minutes = 43 x 60 seconds = 258 seconds.
7 hours = ... second ?

7 hours = 7 x 60 x 60 seconds = 25 200 seconds. (View from hours to seconds the stairs down two times, so it must be multiplied by as much as 2 times the value 60 as well).

1 Week = 7 Days
1 Month = 28 to 31 Days
1 Month = 4 weeks
1 Semester = 6 Months
1 year = 365 to 366 Days
1 year = 52 weeks
1 year = 12 months
1 decade = 10 years
1 century = 100 years
1 millennium = 1,000 years
