1) Write any two numbers whose least common multiple (L.C.M) is 28. A: These two numbers are _ _ _ _ _ _ and _ _ _ _ _. The first combination: 4

7 The second combination: 14

28 2) The teacher has 35 chocolates and 2 1 marshmallow. She wants to give these sweets to some children equally and the rest to them. How many children may the teacher give them? There are: 2, 3, 5, 7, 14, 105, which can only be 2 or 14, 2 can be evenly divided, and 17 is: 35 divided by14 = 2 ... 7 2. The multiple of A. F must be a factor of e. B 1 and a factor of e, f and g at the same time. C. E is the common multiple of f and g. the multiple of D. E is also the multiple of f and g. a is incorrect. Suppose e, f and g are 4, 5 and 20 respectively. The multiple of A.4 is 40, but the factor of 20 is not 20, so A is incorrect. B. 1 is a factor of any number, so b is correct. 4x5 = 20, so c is correct. D.20X2=40 4X 10=40 5X8=40。

If not.

Um, e

F or g is 0.

And e, f and g are integers.

So b is ... a. if the multiple of f is greater than e.

Factors other than e.20 1 0-03-1921:41:27 supplement: Question 2: Remaining: 2 people:1chocolate candy.
