840. 15 = 3 x 5 21 = 3 x 7 40 = 23 x 5 lcm = 23 x 3 x 5 x 7 = 840
3 x 5 = 15 3 x 7 = 21 Combine the factors, eliminating duplicates. 3 x 5 x 7 = 105, the LCM
3 x 5 = 15 3 x 7 = 21 Combine the factors, eliminating duplicates. 3 x 5 x 7 = 105, the LCM
56 = 2^3 * 7 96 = 2^5 * 3 LCM = 2^5 * 3 * 7 = 32 * 21 = 672
The LCM is 252.
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.
LCM of 5 7 21 is 105.
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 ■
3 x 5 = 15 3 x 7 = 21 3 x 5 x 7 = 105, the LCM
Prime factors of 21 are: 3 and 7 Prime factors of 40 are: 23 and 5 LCM = 23*3*5*7 = 840
3=3*1 7=7*1 21=3*7 LCM=(3*7)=(21*1)=21
3 x 5 = 15 3 x 7 = 21 3 x 5 x 7 = 105, the LCM
21 = 3 * 7 60 = 2 * 2 * 3 * 5 LCM is 2 * 2 * 3 * 5 * 7 = 60 * 7 = 420.
210. 30 = 2 x 3 x 5 21 = 3 x 7 lcm = 2 x 3 x 5 x 7 = 210
21 is the LCM of 3 and 7
The Least Common Multiple of 35 and 21 is 105.
