Five multiples of 5 are...
5
10
15

25
ect.
Since 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
4 numbers less than 70 that are multiples of 3 and 5
Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
There is an infinite number of common multiples for 5 and 3. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
The LCM of 3 and 5 is 15. The multiples of 3 are , 6, 9, 12, 15, and so on. The multiples of 5 are 5, 10, 15, and so on. The LCM is 15.
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.
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.
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
Multiples of 50 are the only numbers that are both. All other multiples of 5 aren't.
There are an infinite number of multiples of 3. Five examples may include 3, 6, 9, 12, and 15.
for three 3 6 9 12 for five 5 10 15 20 these both numbers dont share a common denominator in the first 4 multiples
2, 3 and 5 go into multiples of 30.
6, 12, 18, 24, 30
Multiples of 12: 1, 2, 3, 4, 6, 12 Multiples of 5: 1, 5
6 and 12 are multiples of 2 & 3
The first 5 multiples of 3 are as follows: 3, 6, 9, 12, 15
15, 30, 45, 60
