∙ 2010-12-17 22:40:39Since both 3 and 5 are prime numbers, only numbers that are multiples of its product are the numbers that are divisible by both. 15 is the LCM of 3 and 5 and hence all multiples of 15 are divisible by both 3 and 5
They both go into 15 and its multiples
There are 30 two-digit multiples of 3 plus 18 two-digit multiples of 5 minus 6 two-digit multiples of both. Answer: 42
There are three numbers between 10 and 50 which are divisible by both 3 and 5. All numbers that are multiples of 3 and 5 are the multiples of the lowest common multiples (lcm) of 3 and 5 which is 15. The multiples of 15 between 10 and 50 are {15, 30 and 45}, thus there are 3 numbers.
3,6,9,12,15,18,21,24,27,30,33,36,39,42are multiples of 3 5,10,15,20,25,30,35,40,45,50,55,60,65,are multiples of 5
Any number divisible by 15
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.
Multiples of 50 are the only numbers that are both. All other multiples of 5 aren't.
What are 2 multiples that 3 and 5 have in common
There are 33 multiples of 3there are 6 multiples of 3 and 5 = 15So the answer is 33 - 6 = 27 of them.There are 33 multiples of 3there are 6 multiples of 3 and 5 = 15So the answer is 33 - 6 = 27 of them.There are 33 multiples of 3there are 6 multiples of 3 and 5 = 15So the answer is 33 - 6 = 27 of them.There are 33 multiples of 3there are 6 multiples of 3 and 5 = 15So the answer is 33 - 6 = 27 of them.
There are an infinite number of multiples of 3. Five examples may include 3, 6, 9, 12, and 15.
Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
