Since the number is divisible by 3 and 5, it is also divisible by 15. Examine the multiples of 15 which are 15,30,45,60,75,90, and so on. Now find the smallest of these multiples which when divided by 7 will have a remainder of 4. That number is 60. (Other multiples of 15 ...

(1)Solutions:False, 6 is divisible by 3 but is not divisible by 9 (2)True, as 9=3x3. Hence, if a number is divisible by 9, it will also be divisible by 3 (3)False. Since 30 is divisible by both 3 and 6 but is not divisible by 18 (4)True, as 9 x 10 = 90. He...
Any even number can be written as 2m, and any number divisible by 3 can be written as 3n, where m and n are integers. Thus, E^2F^3 equals (2m)^2(3n)^3=(4m^2)(27n^3)=108(m^2n^3), and 108 is the largest number by which E^2F^3 must be divisible.反馈 收藏 ...
