The LCM is 840.
One way to find he LCM of two or more numbers is to list the multiples of each until you reach one that the numbers have in common. For example:14, 28, 42, 56, 70, 84, 98, 112, 126, 140, 154, 168, 182, 196, 21035, 70, 105, 140, 175, 21042, 84, 126, 168, 210210 is the LCM of 14, 35, and 42.
The LCM is 840.
To find the least common multiple (LCM) of 21, 42, and 56, first find the prime factorization of each number. 21 = 3 x 7 42 = 2 x 3 x 7 56 = 2 x 2 x 2 x 7 Then, identify the highest power of each prime factor that appears in any of the factorizations. LCM = 2^3 x 3 x 7 = 56 x 3 x 7 = 1176 Therefore, the least common multiple of 21, 42, and 56 is 1176.
The LCM is: 56
the least common multiple of 42,56, and 140 is 840.
LCM(42, 56, 140) = 840
The LCM is: 840.
The LCM is 840.
lcm of 42,56 and 140 = 840
Least Common Multiple (LCM) for 42 140 is 420.
The Least Common Multiple (LCM) for 42 56 is 168.
