The least common multiple is the smallest positive number that is the multiple of two or more numbers.
3: 3, 6, 9, 12, 15, 18, 21
21: 21
The LCM of 3 and 21 is 21.
the lcm of 3 and 7 is 21 and the lcm of 7 and 21 is 21, so the lcm of 3, 7 and 21 is the lcm of 21 and 21 which is 21.
The LCM is: 105
the answer is 21 due to the fact that 7*3=21 and 21*1=21
3 x 5 = 15 3 x 7 = 21 3 x 5 x 7 = 105, the LCM
The (LCM) Least Common Multiple of 7 and 3 is 21 because that is the LEAST number that both 3 and 7 go into.
the lcm of 3 and 7 is 21 and the lcm of 7 and 21 is 21, so the lcm of 3, 7 and 21 is the lcm of 21 and 21 which is 21.
The Least Common Multiple (LCM) for 3 21 is 21.
The LCM of 3 and 21 is 21
LCM OF 9,3 AND 21 IS 63. CHECK FOR YOURSELF IF YOU ARE NOT SURE.
3 3*7=21 3*30=90 * * * * * That is the Greatest Common Factor, GCF, not the LCM. LCM(21, 90) = 630
3: 3 28: 7, 2, 2 21: 7, 3 LCM = 3x7x4 = 84
3=3*1 7=7*1 21=3*7 LCM=(3*7)=(21*1)=21
The LCM of the given two numbers is 21
21
The LCM is: 21
21 is the LCM of 3 and 7
The LCM is: 21
