The LCM is 105.

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.

105

3 x 7 = 21 5 x 7 = 35 3 x 5 x 7 = 105, the LCM

LCM of 4 7 12 21 is 84

Both of these numbers are divisible by 3 and 7. The factors of 105 is 21 x 5 and that of 147 is 21 x 7. So the LCM is 21 x 35 = 735.

Prime factors of 21 are: 3 and 7 Prime factors of 40 are: 23 and 5 LCM = 23*3*5*7 = 840

The LCM is: 21LCM of 3 & 7 is 21.

3 x 5 = 15 3 x 7 = 21 3 x 5 x 7 = 105, the LCM

3 x 5 = 15 3 x 7 = 21 3 x 5 x 7 = 105, the LCM

The LCM of 7 21 35 is 105

The LCM is 210.

The LCM is 84.

50 = 5*5*2 105 = 5*7*3 so LCM = 5*5*2*7*3 = 1050 1050 = 21*50 and 10 * 105 The LCM is 1050.

3 x 5 = 15 3 x 7 = 21 3 x 5 x 7 = 105, the LCM

3 is a factor of 21, so ignore it. 21 factors to [3 7] 35 factors to [5 7] common factor [7] LCM = 21 * 35 / 7 = 105 ■

since 21 = 3 x 7 and 60 = 2 x 2 x 3 x 5 then the LCM = 2 x 2 x 3 x 5 x 7 = 420

21 = 3 * 7 60 = 2 * 2 * 3 * 5 LCM is 2 * 2 * 3 * 5 * 7 = 60 * 7 = 420.

LCM(21, 7) = 21

The Least Common Multiple of 35 and 21 is 105.

LCM of 5 6 and 21 is 210.

The LCM of 5 and 21 is 105.

21 is the LCM of 3 and 7

105 because if you divide 21 and 15 by three you get 7 and 5 and when you multiply 7, 5, and 3 together you get 105.

The LCM is 420.
