115
The LCM of 23, 5, and 7 is 805.
The Least Common Multiple (LCM) for 23 5 is 115.
46 = 23 * 2 and 115 = 23 * 5So LCM = 23 * 2 * 5 = 230
The LCM is: 72,105
5 = 5 24 = 23 x 3 8 = 23 LCM = 5 x 23 x 3 = 120
factoring 80=2*2*2*2*5 115=5*23 LCM=2*2*2*5*23=1,840
8 = 23 70 = 2 x 5 x 7 LCM = 23 x 5 x 7 = 280
Prime factors of 21 are: 3 and 7 Prime factors of 40 are: 23 and 5 LCM = 23*3*5*7 = 840
1610. 70 = 2 x 5 x 7 115 = 5 x 23 lcm = 2 x 5 x 7 x 23 = 1610
LCM of 5, 8, 10, and 12. 5 = 5 8 = 23 10 = 2 x 5 12 = 23 x 3 LCM = 23 x 3 x 5 = 120 Or, since 5 is the only odd number, the LCM will end with 0. One of the multiples of 12 ending with 0 is 60 or 120. Since 60 is not divided evenly by 8, then 120 is the LCM.
360. 18 = 2 x 32 8 = 23 10 = 2 x 5 lcm = 23 x 32 x 5 = 360
Prime factors of 378: 2, 33 and 7 Prime factors of 360: 23, 32 and 5 LCM: 23*33*5*7 = 7560
