2, 4, 6, 8, 10, 12, 14, 16, 18, 20
The only multiples of 2 are 1 and 2 because it's a prime number, but if you meant first 2 multiples of 20 then it's also 1 and 2.
10, 20, 30 and 40
They are: 10 20 30 and 40
There are 30 multiples of 4 between 5 and 125. Simply divide by 4 and solve for the multiples of 1 between 1.25 and 31.25. That is a range of 2 to 31, and there are 30 multiples. (31 - 2 + 1)
There are two which are 1*10 = 10 and 2*10 = 20
20 and 40
There are four multiples of 11 between 1 and 50 (2-49): 11, 22, 33, 44.
1, 2, 3, 4
10, 20, 30,... To get the multiples, multiply 10 by 1, 2, 3, 4, 5,...
Since 10 is a factor of 20, all multiples of 20 are multiples of 10. This is also true of 1, 2, 4 and 5.
There are six multiples of both 2 and 3 that fall between 1 and 40. They are: 6, 12, 18, 24, 30, 36.
All the multiples of 4 are also multiples of 2.
