well i need to know this Question
those fnctions are only helpful on certain problems. if you could tell me what type of problem it is, i would be able to help you easier. sorrry for not completly knowing
It doesn't. You need common factors for that, not common multiples.
Factors create multiples, multiples break down into factors.
yes because it helps me figure out all the prime numbers!;)
A word problem that involves common multiples could be, "Whatare the common multiples of 10 and 15?"
Common factors: 1 and 2 Common multiples: Any multiple of 132
Factors go into numbers, numbers go into multiples.
2 and 5 are the prime factors that are common to all multiples of 10.
By finding the factors in both numbers and then finding the one that is greatest in common. For example the G.C.F for 45 and 36 is 9.
1 and 2 are common factors. 84 and 168 are common multiples.
