The LCM of 8, 10, and 20 is 40. Multiples of 8: 8, 16, 24, 32, 40, 48...... Multiples of 10: 10, 20, 30, 40, 50, 60...... Multiples of 20: 20, 40, 60, 80 The smallest number that all three numbers go into evenly is 40. Therefore the LCM of 8, 10, and 20 is 40.
40 ... because 5 x 8 = 40 = 2 x 20 = 40
The first five multiples of 4 are 4, 8, 12, 16 and 20. For them to be common, they need to be compared to another set of multiples.
4, 8, 12, 16, 20
4, 8, 12, 16 and 20
They are: 4 8 12 16 20 and 24
The answer is 40 because 20x2=40 and 5x8=40.
2, 4, 6, 8, 10, 12, 14, 16, 18, 20.4, 8, 12, 16, 20.
Multiples of 4: 4, 8, 12, 16, 20 Multiples of 10: 10, 20 Therefore, the answer is 20. (:
