The Least Common Multiple (LCM) of 30, 21, and 7 is 210.
210.(30 * 7 = 210)(21 * 10 = 210)
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.
3 3*7=21 3*30=90 * * * * * That is the Greatest Common Factor, GCF, not the LCM. LCM(21, 90) = 630
210. 30 = 2 x 3 x 5 21 = 3 x 7 lcm = 2 x 3 x 5 x 7 = 210
The LCM is 105.
The LCM is 42
The LCM is 84.
LCM for 7 and 30 is 210.
