3500/42 give 83 quotient,14 remainder next possibility 42*84 =3528. 28 must be added to 3500 then only it will divisible by 42.now check the dividend 3528 with the following divisor 49,56,63

3528/49=72 divisible

3528/56=63 divisible

3528/63=56 divisible

So 3528 is divisible by 42,49,63,56

So 28 must be added 28 is the

339 + 1 = 340,which is exactly divisible.

10056÷23 gives 437 as quotient and 5 as remainder. Dividend-remainder= divisor&times; quotient so 10056-5=23&times;437 gives 10051.our question is least no should be added to 10056 which is divisible by 23. Check next possibility 23&times;438 gives 10074. Now 10056+18= 10074. Therefore 18 is the least number should be added to 10056 to get a number divisible by 23

459684/187 give 2458 and 38 as quotient and remainder. Now next possibility 187 *2459 give 459833. 459833-459684 =149 it should be added. 149 is answer

the rule for divisibility by 9 is that the sum of all digits of the number should should be divisible by 9. So, 3+9+0+6+5= 23. To make is divisible by 9, we think of 27 (as the next number divisible by 9) and that means if we add 4 to any digit of the number, it will be divisible. 39069/9=4341

It is: 36 and so 960/48 = 20

Nope - 1038 is an even number and thus is divisible by 2. Its digits added together total 12 - which is divisible by 3... therefore the original number is also divisible by 3 !!

403÷8 gives 50 as quotient and 3 as remainder. Dividend- remainder=divisor ×quotient 403-3=8*50 which is 400. our value is 403 So increase divisor 8*51=408. 403+5 gives 408. So 5 must be added to 403 to get a no divisible by 8.
