15 & 20 have an infinite number of Common Multiples; the first three are 60, 120 and 180.
Three numbers.
20 pinkgal333:20, 40, 60 are all common multiples.
20
To find the least common denominator (LCD) of one quarter (1/4) and three tenths (3/10), first determine the denominators, which are 4 and 10. The multiples of 4 are 4, 8, 12, 16, 20, and the multiples of 10 are 10, 20, 30. The smallest common multiple of both numbers is 20, so the LCD is 20.
The most common multiples of 4 and 5 are their least common multiple (LCM), which is 20. This means that 20 is the smallest number that can be evenly divided by both 4 and 5. Other common multiples include 40, 60, 80, and so on, as they are all multiples of 20.
10 and 15 15 and 20 20 and 25
60, 120 and 180
The common multiples of 9, 15, and 20 are an infinite set of multiples of their least common multiple, which is 180. so the common multiples of 9, 15, and 20 are 180, 360, 540, 720, 900, 1080, 1260, 1440, 1620, 1800, and so on.
60 and all its multiples
The multiples of 20 are 20, 40, 60, 80, 100, 120... The multiples of 30 are 30, 60, 90, 120, 150... The multiples of 15 are 15, 30, 45, 60, 75, 90, 105, 120, 135... The common multiples of 20, 30, and 15 are 60, 120, 180, 240...
LCD= 60
Ans: 15, 30 and 45 Prime factorization of 3 and 15 3: 3 15: 3 x 5 15, 30 and 45. Hi My names Bob
The LCM is 60
60 and 8,220
What are the first three common multiples of four and five
10, 20, 30 The common multiples of 5 and 10 are multiples of their lowest common multiple. The lcm of 5 and 10, is 10. Thus the first three common multiples are 10, 20, 30.
