All the common multiples of a set of numbers are the multiples of their lowest common multiple: lcm(5, 8, 10) = 40 → first three common multiples are 40, 80, 120
Well, honey, common multiples of 5 and 10 are numbers that both 5 and 10 can divide evenly into. So, grab your calculator and start counting by 10s until you hit a number that is also divisible by 5. Spoiler alert: the first few common multiples are 10, 20, 30, 40... you get the idea. Happy math-ing!
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.
Each common multiple of 9 and 10 occurs exactly once (in the list of common multiples), so there is no common multiple that occurs the most. All common multiples of 9 and 10 are the multiples of their least common multiple which is 90.
2 and 5 are the prime factors that are common to all multiples of 10.
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.
