4
40 is divisible by 1, 2, 4, 5, 8, 10, 20 and 40.
No number between 20 and 40 is divisible by all 4 numbers. The smallest number divisible by all 4 of those numbers is: 56
Every other number: 8, 16, 24, 32, 40... No, a number can be divisible by 4 but not divisible by 8; an example is 12.
40 is nearest to 39 and is exactly by divisible 4
yes,like 40 is divisible by 4 ten times
The number is 48.
the number is 48
The simplest way is to divide 748 by 4 and show that there is no remainder. That proves it. A longer, but more general proof is as follows: 25*4 = 100 so 100 is dividsible by 4. By the distributive property, you can show that any number of hundreds (eg 700) is divisible by 4. So, to prove that 748 is divisible by 4, it is only necessary to show that the number formed by the last two digits (48) is divisible by 4. This is easy, since 12*4 = 48. The second method is not much of an advantage with a number like 748, but it would be if you were asked to prove that 75612349248 was divisible by 4!
What we want to find is the number in that list that is not divisible by 4. This number would be 18, your answer.
48.
A number is divisible by 4 if the last two digits are divisible by 4.A number is divisible by 4 if the last two digits are divisible by 4.A number is divisible by 4 if the last two digits are divisible by 4.A number is divisible by 4 if the last two digits are divisible by 4.
First, let's find the multiples of 3 between 40 and 50. You can tell if any number is divisible by 3 by adding the digits and seeing if those are divisible by 3. (30 => 3+0 =3, thus 3 is divisible by 3. 31 => 3+1 =4, thus 31 is not.) We see that 40 and 41 are not divisible. What about 42? 4+2 = 6 which is divisible by 3, thus 42 is divisible by 3. Multiples of 3 must by 3 apart, so we can find the others by adding 3 to 42: 45, 48 Since the next number divisible by three is 51, we stop here. What about divisible by 4? Since 40/4 =10, we know 40 is divisible by 4. We can again add 4 to find the others: 44, 48. Thus we have the multiples of 3 between 40 and 50: 42, 45, 48 and the multiples of 4: 40, 44, 48. Since they have 48 in common, Sue must have been thinking of 48.
