Answer:
2,772
Explanation:
First we find the LCM (Least common multiple) of the given numbers.
2 | 22, 36, 42
2 | 11, 18, 21
3 | 11, 9, 21
3 | 11, 3, 7
7 | 11, 1, 7
11 | 11, 1. 1
| 1, 1, 1,
LCM of 22, 36, 42 = 2*2*3*3*7*11 = 2,772
Thus, the lowest number of four digits that can be divided by 22,36,and 42 is 2772.
