A common factor is '7' 3 x 7 = 21 7 x 7 = 49 '7' appears in both multiples.
The Least Common Multiple (LCM) for 49 63 21 is 441.
The common multiples of 7, 14, and 21 are the infinite set of multiples of their least common multiple, which is 42. So the common multiplesof 7, 14, and 21 are 42, 84, 126, 168, and so on.Any multiple of 42.
The least common multiple of the numbers 21, 48 and 49 is 2,352.
14, 21, 28, 35, 42, 49, 56, 63 . . .
LCM of 21 & 49 is 147, so all multiples of 147 are common multiples of 21 & 49.
LCM(21, 49, 56) = 1176
Multiples 21: 1,3,7,21Multiples 49: 1,7,49
147, 294, 441 and so on.
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.
21, 28, 35, 42, 49
It is 7!

It is not possible to write all the common multiples of two or more numbers.However, we can write as many as we want but first of all we have to find L.C.M. of 49 and 14 and the answer is 98.Also, multiples of 98 are the common multiples of 49 and 14.It means that multiples of least common factor of two or more numbers are the common multiples of the numbers.So, first five common multiples are 98x1, 98x2, 98x3, 98x4 and 98x5.
They are: 21, 28, 35, 42 and 49
A common factor is '7' 3 x 7 = 21 7 x 7 = 49 '7' appears in both multiples.
