6, 12 and 18
I am guessing you want common factors. That is to say factors common to 10 and 30 The common factors would be: 1,2, 5, and 10, but there only 4 that are common. 15 and 30 are factors of 30 so if you add those you have 6 factors.
The only common factor of 3 and 5 is 1.
The factors of 8 are 1, 2, 4, and 8. The factors that add up to 10 are 2 and 8.
90 and 6 60 and 36 eight twelves sixteen sixes twenty-four fours thirty-two threes forty-eight twos ninety-six ones
Common three-digit multiples of 27 and 11 are 297, 594 and 891. None of their digits add up to 10.
-- Find a common denominator. (It will be a number of which all three denominators are factors. The best choice is their least common multiple.) -- Change the fractions to their equivalents with the common denominator. -- Then add their numerators to get the numerator of their sum.
Factors are multiplied, not added. The question needs to be something like, "Which two factors of thirty add up to 11?" The answer would then be 5 and 6.
thirty-three
Three feet and three inches is a total of thirty-nine inches. There are twelve inches in a foot, multiplied by three is thirty-six and add the three extra inches and it comes to thirty-nine inches.
A common denominator is 32.
26+7
negative thirty negative thirty one and negative thirty two
find a common denominator for all three and then add all of the numerators together and keep the same denominator

Multiples don't add. Addends add, like 13 + 14 + 15 = 42 but I suspect you want factors, specifically prime factors. 2 x 3 x 7 = 42
x-63=-130 add 63 x=-67
Neither. Factorise and then multiply a subset of factors.
