Not unless you're dealing with them as fractions.
1, 2, 7, 3 and 6 are not divisible by 4 and/or 9. 12736 is divisible by 4 but not by 9.
1, 4 or 7
2463. The trick is that a number is divisible by 3 if and only if the sum of its digits is divisible by 3. 1+3+2+4 = 10 (not divisible by 3), while 2+4+6+3 = 15 (divisible by 3).
n = 1 or 4 or 7 and the word is divisible, not divisable.
7 + 4 + 1 = 12 which is divisible by 3, so 741 is divisible by 3 741 is odd, all multiples of 4 are even, 741 is not divisible by 4 (Alternatively 4 x 2 + 1 x 1 = 9 which is not divisible by 4, so 741 not divisible by 4) All multiples of 5 end with 5 or 0, 741 ends with 1, so 741 not divisible by 5 To be divisible by 6, the number must be divisible by 2 (even) and divisible by 3.741 is odd, so not divisible by 2, so 741 is not divisible by 6 7 + 4 + 1 = 12 which is not divisible by 9, so 741 is not divisible by 9 All multiples of 10 end with 0, 741 ends with 1 so 741 is not divisible by 10 Summary: 741 is divisible by 3, but not by 4, 5, 6, 9 nor 10.
Because 21 is a multiple of 1, 3, 7 and 21.
A number is divisible by 6 if it is divisible both by 2 and 3 1240 is even then is divisible by 2 1+2+4+0 = 7 which is not divisible by 3 then 1240 is not divisible by 3 Thus 1240 is not divisible by 6
It is divisible only by 3; It is not divisible by 2, 4, 5, 6, 9, 10. 17211 is odd, so not divisible by 2, 4, 6 nor 10. 1 + 7 + 2 + 1 + 1 = 12 which is divisible by 3, so 17211 is divisible by 3, but 12 is not divisible by 9, so 17211 is not divisible by 9. 17211 does not end in 5 or 0 so not divisible by 5

Add together the digits of the number to be divided by 3. If the sum is 3 or a multiple of 3 then the number is divisible by 3. Example : 5681 ; 5 + 6 + 8 + 1 = 20 which is not a multiple of 3 so 5681 is NOT divisible by 3. 477 ; 4 + 7 + 7 = 18 which is a multiple of 3 so 477 is divisible by 3. NOTE : When adding the digits, the digits of the total can be summed to determine if the original number is divisible by 3. In the example 4 + 7 + 7 = 18 then 1 + 8 = 9, and 9 is a multiple of 3 so confirming that 477 is divisible by 3.
420
Not evenly. An easy way to tell is that its digits add up to 7, a number which is not divisible by 3.
