The answer would be 750,000.
18, 36, 54, 72, 90.
Since the GCF of 5 and 6 is 1, their LCM is their product. The first five multiples of 30 are 30, 60, 90, 120, 150
What about them?
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.
The Least Common Multiple of 625, 256: 160,000
The first five nonzero multiples of 6 are 6, 12, 18, 24 and 30.
75, 150, 225, 300, 375
84, 168, 252, 336, 420
45, 90, 135, 180, 225
18, 36, 54, 72, 90.
Take the first number. Add it to itself. Keep adding that number to the total three more times. The first five nonzero multiples of 9 are 9, 18, 27, 36, and 45. Put another way, let each number equal x. The first five nonzero multiples of x are 1x, 2x, 3x, 4x and 5x.
40, 80, 120, 160, 200
57, 114, 171, 228, 285.
5, 10, 15, 20, 25, 30, 35, 40.
30, 60, 90, 120, 150.
The first five multiples of 10 are 10,20,30,40,50.... 1 * 10 = 10 2 * 10 = 20 3 * 10 = 30 4 * 10 = 40 5 * 10 = 50
