402. It is the first number after 400 for which the digital root (the sum of its digits) is divisible by 3.
The digital root being divisible by 3 is a test for divisibility by 3.
1, 2, and 53, have their first common multiple of 106.
400 is one such multiple.
Here are three: 1100 330 660
Find either the least common multiple, or any common multiple, of those three numbers. One way to get a common multiple is to simply multiply the numbers together. Then try multiplying that multiple by different integers, until you find one that is greater than 200.
42
The smallest multiple of three that is greater than one hundred is 102. This is because 100 divided by 3 gives a quotient of 33 with a remainder, and the next whole number multiple of three is 34, which results in 102 (34 x 3 = 102).
