60 and its multiples
lcm(2, 3, 5) = 30 → 2 digit common multiples are 30, 60, 90.
20 pinkgal333:20, 40, 60 are all common multiples.
2 and 5 are the prime factors that are common to all multiples of 10.
Both 2 and 5 are prime numbers so their product 2 x 5 = 10 is the Lowest (or Least) Common Multiple. The common multiples of 2 and 5 are therefore any number which is a multiple of 10.
The common multiples of 2 and 5 are numbers that can be divided evenly by both 2 and 5. The common multiples of 2 and 5 are multiples of their least common multiple (LCM), which is 10. Therefore, the common multiples of 2 and 5 are all multiples of 10. Similarly, the common multiples of 2 and 6 are multiples of their LCM, which is 6. Therefore, the common multiples of 2 and 6 are all multiples of 6.
60 and its multiples
lcm(2, 3, 5) = 30 → 2 digit common multiples are 30, 60, 90.
The first two common multiples of 235 is 5 and 47.
10 and 20

10,20,30
Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the highest amount of each factor. 2 x 3 x 5 x 7 = 210, the LCM Other common multiples can be found by multiplying the LCM by successive counting numbers.
The common multiples of 2 and 5 are 10, 20, 30, 40, etc.In detail:A common multiple is a number divisible by both (or all) numbers: 2 and 5, here.Knowing that all numbers divisible by 2 have a 0, 2, 4, 6, or 8 in the ones place combined with the knowledge that all numbers divisible by 5 end with 0 or 5 (excluding 0 in both cases), we can say the only multiples of each number that are common to both are numbers that end with 0.Another way of analyzing this problem is to say that both 5 and 2 are factors. 10 is clearly a multiple of 5 and 2 because 2(5)=10. Any number divisible by 10 is thus also divisible by 2 and 5. All numbers divisible by 10 end in 0. Thus, a number ends in 0 if and only if it is divisible by 2 and 5.Answer: Common multiples of 2 and 5 end with zero.
The common multiple for 2 and 5 is 1 cause both of the numbers are prime.
They are 10 and 20
Multiples of 2 are: 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30 simply adding 2 multiples of 5 are: 5,10,15,20,25,30 simply adding 5 multiples of 2 and 5 are the ones that are common between the two. some of them would include 10,20,30,40,50,60,70,80,90,100
