70, 140, 210, 280, 350, 420, 490
30 and 60
99 of them.
factoring 5 factored =1*5 12 factored =2*2*3 no common factor so the LCM is 60 the next multiples would be 120 and 180
The first 5 common multiples are the first 5 multiples of their lowest common multiple (LCM) LCM(9, 10) = 90 → first 5 common multiples are 90, 180, 270, 360, 450.
The common multiples of 2, 4, 5, 10, and 15 are the multiples of the set's LCM, which is 60. Therefore, the common multiples of 2, 4, 5, 10, and 15 are 60, 120, 180, 240, 300, 360, and so on. There is an infinite number of common multiples for 2 5 10 4 and 15. 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). However, the least or lowest common multiple (LCM) of 2 5 10 4 and 15 is 60.
They are: 500, 1000, 1500, 2000 . . .
30 is the Least Common Multiple of 2, 5 and 6. All multiples of 30 are divisible by 2, 5 and 6
60 and its multiples
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.
lcm(2, 3, 5) = 30 → 2 digit common multiples are 30, 60, 90.
The first two common multiples of 235 is 5 and 47.
If that's 34 and 5, you're looking for 500 multiples of 170 which starts with 170, 340, 510, 680 and keeps adding 170 until you get to 85,000. If that's 3, 4 and 5, you're looking for multiples of 60 which starts with 60, 120, 180, 240, 300, 360 and ends with 30,000.
10 and 20
10
10,20,30
The common multiple for 2 and 5 is 1 cause both of the numbers are prime.
They are 10 and 20
