To find the numbers between 10 and 50 that are multiples of both 3 and 5, we need to find the numbers that are multiples of the least common multiple of 3 and 5, which is 15. The multiples of 15 between 10 and 50 are 15, 30, and 45. Therefore, there are 3 numbers between 10 and 50 that are multiples of both 3 and 5.
The sum of all multiples of 3 below 500 is the sum of 3 + 6 + ... + 498 = 41583The sum of all multiples of 5 below 500 is the sum of 5 + 10 + ... + 495 = 24750Depending upon the interpretation of "of 3 and 5", the answer is one of:The sum of all multiples of both 3 and 5 below 500 is the sum of 15 + 30 + ... + 495 = 8415The sum of all multiples of 3 below 500 and all multiples of 5 below 500 is 41583 + 24750 = 66333Since the multiples of both 3 and 5 (that is 15, 30, ...) have been counted twice - once in the multiples of 3 and once in the multiples of 5 - the sum of all multiples of 3 or 5 or both below 500 is 41583 + 24750 - 8415 = 57918I have emphasised the word below with regard to 500 since 500 is a multiple of 5, but 500 is not below (less than) itself, that is the multiples are of the numbers 1, 2, 3, ..., 499. If the question was intended to mean less than or equal to 500, add an extra 500 to the multiples of 5 above, making the sum of the multiples of 5 be 25250 and the final sums (1) 8415, (2) 66833, (3) 58418.
The multiples of 2 between 7 and 15 are 8, 10, 12, and 14.
What are the odd multiples of 3 between 10 and 40? 15, 21, 27, 33, 39. What multiples of 10 is 34 between?
18,21,24,27.
The multiples of five between five and 26 are: 10, 15, 20, 25.
First, we want to find the first multiple of 7 above 100. This is 105. 105/7=15. Next, we want to find the last multiple of 7 below 500. That would be 497/7=71. Now, we perform 71-15=56. Since our list was inclusive, meaning that we counted both 105 and 497, we add one to get 57 multiples of 7 between 100 and 500.
The first 15 multiples of 70: 70, 140, 210, 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050 . . . ∞
To find numbers between 55 and 101 that are multiples of 3, 10, and 15, we need to find the numbers that are common multiples of these numbers within the given range. The common multiples of 3, 10, and 15 are numbers that are divisible by the least common multiple (LCM) of these numbers, which is 30. Therefore, the numbers between 55 and 101 that are multiples of 3, 10, and 15 are 60, 90, and any other multiples of 30 within that range.
