lowest positive integer that is divisible by the first 7 positive integer multiples of 5
We need to find the LCM of 5, 10, 15, 20, 25, 30, and 35
5 | 1, 2, 3, 4, 5, 6, 7
5 | 1, 2, 3, 4, 1, 6, 7
3 | 1, 2, 1, 4, 1, 2, 7
2 | 1, 1, 1, 2, 1, 1, 7
2 | 1, 1, 1, 1, 1, 1, 7
7 | 1, 1, 1, 1, 1, 1, 1
LCM = (5)(5)(3)(2)(2)(7) = 2100
Hence, option D
