3 digit numbers less than 300 that are divisible by 2 and 5 are be numbers ranging from 100 to 290. 120, 150, 180, 210, 240, and 270 are divisible by 3, so those are crossed off the list. The sum of the digits is 7. 160 and 250 are possible answers. 1+6+0 = 7 and 2+5+0 = 7. 160/2 = 80 and 160/5 = 32. 250/2 = 125 and 250/5 = 50. I can either be 160 or 250.
there is no number less than 49 between 1 and 100 that if multiplied by 2 will have a 3-digit product no number less than 50, actually
160, 250
Three numbers that fit these criteria are:108, 144, and 180.
No. (Assuming a three digit number is in the range 100-999 and excludes leading zeros, that is 080 does not count as it is really 80 which is a two digit number) To be divisible by 11, the difference in the sums of the alternate digits of the number must be divisible by 11 (or 0). For a three digit number, this means that the sum of the first and last digits less the second digit must be a multiple of 11 (or 0). For a three digit number with all the digits the same, this calculation results in the value of one of the digits (eg 333 → 3 + 3 - 3 = 3) which will not be 0, and cannot be a multiple of 11 as a single digit is less than or equal to 9 which is less than 11 and thus not a multiple of 11.
There are 278 5-digit numbers less than 20,000 that are divisible by both four and nine.
