A certain integer n is a multiple of both 5 and Must n be a multiple of 15?
选项
答案
15
解析
The first step in solving this problem is to find the Least Common Multiple(LCM)of 5 and 9. Because a multiple of 5 must have either a 5 or a 0 in the digits place, and 9 × 5 is the first multiple of 9 with a 5 in the digits place, 9 × 5 = 45 must be the LCM. Therefore, n must be a multiple of 15, since 45(one possible value of n)is a multiple of 15.
