A common multiple of 9 and 21 is a number of the form 63*k where k is an integer.
The next common multiple of 9 and 21 can be found by determining their least common multiple (LCM). The LCM of 9 and 21 is 63, as it is the smallest number that both 9 and 21 divide evenly into. Therefore, the next common multiple of 9 and 21, after 0, is 63.
A common multiple of 9 and 21 is 63
The LCM of 9, 18, and 21 is 126It is: 126
The least common multiple of 7 , 9 , 21 = 63
21 = 7 x 3 , 9 = 3 x 3 ; for the Least Common Multiple (LCM), 21 already is a multiple of 7. 21 & 9 have a common factor of 3, so LCM = 21 x 3 = 63
There is an infinite number of common multiples for 9 and 21. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
The Least Common Multiple (LCM) for 9 21 10 12 is 1,260.
