The least common multiple of two or more numbers is equal to the product of common factors and uncommon factors of all the numbers.
Factors of 8 = 2 x 2 x 2
Factors of 12 = 2 x 2 x 3
Factors of 16 = 2 x 2 x 2 x 2
Common factors of 8, 12 and 16 = 2 x 2 x 2
Uncommon factors of 8, 12 and 16 = 3 x 2
Least common multiple of 8, 12 and 16 = common factors x uncommon factors
Least common multiple of 8, 12 and 16 = 2 x 2 x 2 x 2 x 3
Least common multiple of 8, 12 and 16 = 48
Factors of 8 = 2 x 2 x 2
Factors of 12 = 2 x 2 x 3
Factors of 16 = 2 x 2 x 2 x 2
Common factors of 8, 12 and 16 = 2 x 2 x 2
Uncommon factors of 8, 12 and 16 = 3 x 2
Least common multiple of 8, 12 and 16 = common factors x uncommon factors
Least common multiple of 8, 12 and 16 = 2 x 2 x 2 x 2 x 3
Least common multiple of 8, 12 and 16 = 48
