So I have math homework and i thought you "were" going to give use answers till I read Note: This site id intended to help students and non-stidents understand and practice math.we do not condone cheating. Users attempting to abuse the system will be permantly blocked form futher use. I was like this is a pretty decent site any site that helps you cheat is like So fake ! But now i know how to do this I was just so lazy to pay attention but now I know do i will help you guys out . So you always start with one times the number right ? So that will be your first common factor next we know that 75 is NOT a even number so it cant deal with 2,4,6,8,maybe 9 it will mostly be common to the numbers that end with a 5 or zero . so one times 15 ,and 3 five oh and also my math homework is find the common factors of 15 , and 75 so im actaully doing the 15 first . 1 times 75 5 times 15 You can mostly find your answers by dividing or multiplying its not hard
