Yes, because the digits of 261 add up to a multiple of 3.
Common three-digit multiples of 27 and 11 are 297, 594 and 891. None of their digits add up to 10.
They are 45, 90, 135, 180, 225, 270, 315, 360, 405, and 450.
There isn't one for 3. If your teacher or someone assigned you make a factor tree for 3 they're wrong. Unless you want to use 1x3 but that doesn't count.
No factor of 9 has three digits. 450 is a three-digit multiple of 150 (and of 9) with a digit sum of 9.
If that is the case, then three is a factor of the original number.
Three is.
If the sum of the digits is a multiple of three, the whole number is a multiple of three.
300, 600 and 900.
what is the number that has three digits less than 140 has7 factor the sum of the digits of the number is less than 9
Easier than what? The easiest way to produce a three-digit number that is a multiple of 3 (has 3 as a factor) is to make sure the digits total to a multiple of 3. 123, 555, 498 are all multiples of 3.
114 beacause it's three digits a factor of seven even
The first squared number that is a multiple of 10 is three digits.
To be a multiple of 6 a number must be even and a multiple of 3.356 is not a multiple of three. The short cut to that is if the digits add up to a multiple of three then the original number is a multiple of 3.
Because they're in multiples of three - a quick way to tell if a number is a multiple of three is to add up the digits and see if the digits add up to a multiple of three e.g 576, 5+7+6=18, 1+8=9, 9 is a multiple of three
We can tell by applying the divisibility rules that 6 is not a factor of 208. For 208 to be a multiple of 6, it would have to be even and a multiple of three. Since the digits of 208 don't total a multiple of three, 208 is not a multiple of three and can't be a multiple of 6.
