I cannot say that nowadays with the use of calculators and computer that we 'need' to figure out the factors of a number in real life. One use I can think of is to splitting the bill among friends. In school, the use would be during an exam, it would be handy to break large numbers into smaller ones when you are asked to simplify a fraction.
One other practical use is approximation. Sometimes I want to check whether my calculator results make sense -- I can use factors and multiples to reduce the numbers to their simplest form and get an approximate answer. Other times, I just need an approximate answer in my head without the benefit of a calculator.
It is always useful to know about factors and multiples.
Factors go into numbers, numbers go into multiples.
Factors go into the number. The number goes into multiples.
Multiples. Numbers have an infinite number of multiples.
Factors: 1 and 43 Multiples 43, 86, 129 and so on.
multiples: Least Common Multiple
Factors create multiples, multiples break down into factors.
Factors are useful when you're trying to reduce fractions. Multiples are useful when you're trying to find a least common denominator.
the factors and multiples of 396 are 1,2,3,4,6,9,11,12,18,22,33,36,44,66,99,132,198,396
Factors: 1,2,3,6 Multiples: 6,12,18,24 and so on.
Factors go into numbers, numbers go into multiples. Divisibility shows what factors come out of what multiples.
Factors of the number will also be factors of the number's multiples. Multiples of the number will also be multiples of the number's factors.
