This gives us 105* 2=210 which is divisible by 3, 5, and 7 and is also between 200 and 300. The number is 210.若一个数能被3,5和7整除,那么它一定能被它们的最小公倍数整除.因为3,5 和7除了1之外没有共同的因子,所以这三个数的最小公倍数是它们的乘积.因为3* 5* 7=105不在200到300...
What is the smallest positive integer that is divisible by 1, 2, 3, 4, and 5( ).A.720B.360C.120D.60 答案 DSince 4 is already a multiple of 2, the 1 c.m. of 1, 2, 3, 4, 5 is 3×4×5=60.能被1,2,3,4,5整除的最小正整数是( ).A.720 B.360 C.120 D.60因为4能...
If this is a T-F question, the answer is false. It is true that if a number is divisible by 6, it also divisible by 3. This is true because 6 is divisible by 3. However, the converse -- If a number is divisible by 3, it is divisible by 6, is false. A counterexample is 15...
If two numbers are divisible by 3, is their sum divisible by 3? What are whole numbers? What are all the whole numbers? What are the whole numbers from 1 to 100? The number of integers from 1 to 10000 (inclusive) which are divisible neither by 13 nor by 51 is?
To find a number between 120 and 130 that is divisible by 3 and has a digit sum divisible by 4, we first consider the numbers in that range: 121, 122, 123, 124, 125, 126, 127, 128, 129. Next, we calculate the digit sum of each number: 121 (1+2+1=4), ...
