All numbers that have 3 and 13 as factors are multiples of the LCM of 3 and 13 which is 39.
The 4 digit numbers are 1000 to 9999 and of these, the multiples of 39 are:
1000 ÷ 39 = 2525/39 ⇒ first multiple of 39 greater than or equal to 1000 is 26 x 39 = 1014
9999 ÷ 39= 25615/39 ⇒ last multiple of 39 less than or equal to 9999 is 256 x 39 = 9984
Thus the multiples from 26 to 256 of 39 are the 4 digit numbers with 3 and 13 as factors.

How many 3 digit numbers have even no of factors?
878 three digit numbers have an even number of factors. Every factor of a number has a pair, so there ought to be an even number of factors for every number. However, if a pair of the factors are the same number, then there will be an odd number of factors, that is if the number is a perfect square. Assuming three digit numbers are 100 to 999: From 100 to 999, the perfect squares are 102 = 100 to 312 = 961, a total of 31-10+1 = 22 numbers. So of the 999-100+1 = 900 three digit numbers, 22 have an odd number of factors, so 900-22 = 878 have an even number of factors.
