The common multiple for 2 and 5 is 1 cause both of the numbers are prime.
30 is the Least Common Multiple of 2, 5 and 6. All multiples of 30 are divisible by 2, 5 and 6
They are 10 and 20
The common multiples of any numbers are multiples of their lcm. The lcm of 2, 3, 4, 5 & 6 is 60 Thus the next four common multiples are 2 x 60, 3 x 60, 4 x 60 & 5 x 60 which are 120, 180, 240 & 300
The common multiples of 5 and 6 are the multiples of their lowest common multiple (which is 30), so there are infinitely many common multiples of 5 and 6. The first five are: 30, 60, 90, 120, 150.
Common multiples of 7 and 5 include 35, 70, 140, etc.
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
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
10,20,30
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
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.
