Prime+Numbers

Hey guys, my topic is to help your difficulties and weakness about primes numbers. They are really helpful and fun to learn.

PRIME number in math are number that can only divide itself with the number one. For example the number three has only one divisor which is one and itself. These are the list of prime numbers: 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,41,43,47,53,59,61,67,71,79,83,89,97 These are all the prime number which u can find from one to hundred,now can u try to find nine more after the list I have made.

The prime number helps u in different genres of math for instance it helps really well with the factor tree because the answer must be a prime. to find the answer in the factor tree just multiply all the primes together. You do this to find out the factor of the number. This is an example of a factor tree,start your factor tree by the number you want to find the factor then distribute into two numbers that when multiplied, gives the answer of the number above. It stop by the last one being a prime. Then multiply all the primes together.
