2 yes, 3 no.
To determine if 42 is divisible by 3, you can add up the digits of 42 (4 + 2 = 6) and check if the sum is divisible by 3. Since 6 is divisible by 3, then 42 is also divisible by 3. This is based on the rule that a number is divisible by 3 if the sum of its digits is divisible by 3.
1262 is even, so 1262 is divisible by 2. 1 + 2 + 6 + 2 = 11 which is not divisible by 3 nor 9, so 1262 is not divisible by 3 nor 9.
Answer - How do you tell if a number is divisible by 3?you add all the digits in the number and see if that number can be divided by 3 Answer - A whole number is divisible by 3 if the sum of its digits is divisible by what?Three (3) Examples:* 27 -- 2+7=9 * 13452 -- 1+3+4+5+2=15 -- 1+5=6If the sum of the digits is divisible by 3, the number is also divisible by 3. Or just do the division.
3 yes, 2 no.
No. 741 is divisible by: 1, 3, 13, 19, 39, 57, 247, 741.
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.
741 is divisible by 1, 3, 13, 19, 39, 57, 247, 741
No, but I suspect you want to know if 741 is divisible by that string of numbers. Out of that group, 741 is only divisible by 3.
247, 494 (=247*2), 741 (=247*3) etc.
The multiples of 741 (which are infinite) are all divisible by 741, including these: 741, 1482, 2223, 2964, 3705, 4446, 5187, 5928, 6669 . . .
Not evenly. 741 ÷ 6 = 123.5
No.
No.
It is divisible by three which gives you 247
not exactly 247 x 3 = 741 248 x 3 = 744 743 / 3 = 247.667
123 is not divisible by 2 it is divisible by 3
