21 and 28
Multiples of 7 include 7, 14, 21, 28 and so on. For them to be common, they need to be compared to another set of multiples.
Multiples of seven include 7, 14, 21, 28, 35, 42, 49 and so on. For them to be common, they need to be compared to another set of multiples.
The multiples of 28 include 28, 56 and 84. For them to be common, they need to be compared to another set of multiples.
4, 8, 12 and so on. 7, 14, 21 and so on. Common multiples include 28, 56, 84 and so on.
Multiples of 7 include 7, 14, 21, 28, 35 and so on. For them to be common, they need to be compared to another set of multiples.Itself and any other multiples of 7
Multiples of 28 include 28, 56 and84. For them to be common, they need to be compared to another set of multiples.
LCM of 21 & 49 is 147, so all multiples of 147 are common multiples of 21 & 49.
The common multiples of 21 and 28 are 84, 168, 252, 336, ... and so on, never ending; so there is no real Highest Common Multiple.Do you mean:Highest Common Factor - the highest number which divides both 21 and 28 which is 7; orLowest Common Multiple - the lowest number which is a multiple of both 21 and 28 which is 84.
The four multiples of seven are 7, 14, 21, and 28.
there are infinite amount of common multiples.
Multiples of 7 that are less than 60 are 7, 14, 21, 28, 35, 42, 49, 56.Multiples of 14 that are less than 60 are 14, 28, 42, 56. Common multiples that are less than 60 are 14, 28, 42, and 56.
