The Least Common Multiple (LCM) of 4, 5, and 7 is the smallest multiple that all three numbers share. To find the LCM, you can start by listing the multiples of each number: 4 (4, 8, 12, 16, 20...), 5 (5, 10, 15, 20...), and 7 (7, 14, 21...). The smallest multiple that all three numbers share is 140, so the LCM of 4, 5, and 7 is 140.
The LCM of 2 and 3 is 6. The LCM of 2 and 4 is 4. The LCM of 5 and 7 is 35. The LCM of 7 and 9 is 63.
140
The LCM is 840.
the LCM of 4/5/6/7/8/9 is 75
2^6 3^7 5 26375
The LCM of 4, 9, 5, and 7 is 1,260.
The LCM is 420.
The LCM is 420.
The LCM is 1260.
For 7, 5, 4, 3, 2 the LCM is: 420
4 and 5 and 7 have no common factors. So their LCM is 4 x 5 x 7 = 140.
LCM(4, 5, 7) = 140
The least common multiple of 4 , 7 , 5 , 3 = 420
The LCM is: 1,260
The LCM is: 840
the lcm of 1 2 3 4 5 6 7 is 420
lcm(2, 3, 4, 5, 6, 7, 8) = 840
