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 least common multiple of 21, 42, 63, and 105 is 630.
The least common multiple (LCM) of 21 and 42 is 42.
The least common multiple of 14 and 21 is 42.14, 28, 42, 56 ...21, 42, 63, 84, ...
Least Common Multiple (LCM) for 14 21 6 is 42.
LCM= least common multiple. so the LCM of two numbers 21 and 14 is 42. because 42 is the least multiple that both numbers have in common! =) your welcome!, anytime!
The least common multiple of 6 , 21 = 42
The least common multiple of 21, 42, 63, and 105 is 630.
