The common multiples of any two or more numbers are the multiples of their lowest common multiple.lcm(3, 4, 5) = 60→ first three common multiples are:60 x 1 = 6060 x 2 = 12060 x 3 = 18060, 120, 180
The common multiples of 3, 4, and 8 are numbers that are divisible by all three of these numbers. To find the common multiples, we first list the multiples of each number: Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, ... Multiples of 4: 4, 8, 12, 16, 20, 24, ... Multiples of 8: 8, 16, 24, 32, ... The common multiples of 3, 4, and 8 are 24, 48, and so on, as they are the numbers that appear in the lists of multiples of all three numbers.
All nonzero numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples. 36 is a multiple of 4. 36 is a multiple of 9. 36 is a common multiple of 4 and 9.
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
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.
