No, 7 is not divisible by 3. In division, when a number is divisible by another number, it means that the division results in a whole number without any remainder. When you divide 7 by 3, you get 2 with a remainder of 1, which means 7 is not divisible by 3.
18444 is divisible by 3: 18444/3 = 6148. 18444 is not divisible by 5: 18444/5 = 3688.8 18444 is divisible by 6: 18444/6 = 3074 18444 is not divisible by 7: 18444/7 = 2634.857142 18444 is not divisible by 10: 18444/10 = 1844.4
Yes, 75 is divisible by 3. A number is divisible by 3 if the sum of its digits is also divisible by 3. In this case, 7 + 5 = 12, and 12 is divisible by 3 (12 ÷ 3 = 4), so 75 is divisible by 3.
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).
Oh, what a lovely question! Let's see, we can find the numbers divisible by 3 first, which are 33 numbers, and the numbers divisible by 7, which are 14 numbers. But wait, some numbers are divisible by both 3 and 7, so we must be careful not to count them twice. In the end, there are 47 numbers between 1 and 100 that are divisible by 3 or 7. Happy counting!
The divisibility rule for 3 is as follows: If the sum of the digits of a number is divisible by 3 then the number is divisible by 3. For example, the number 21 is divisible by 3 since 2+1=3, and 3 is divisible by 3. The number 49 is not divisible by 3 since 4+9=13, and 13 is not divisible by 3.
3*21 = 63 so 63 is divisible by 3 7*9 = 63 so 63 is divisible by 7.
a number is divisible by 12 if the number is also divisible by both 3 and 7. You mean a number is divisible by 21 if it is divisible by 3 and 7.
NO. 313 is not divisible by 3.A number is divisible by 3 if the sum of the digits is divisible by 3.313 = 3 + 1 + 3 = 7Note: 7 not divisible by 3 thus, 313 is not divisible by 3.
Not evenly. An easy way to tell is that its digits add up to 7, a number which is not divisible by 3.
Because 21 is a multiple of 1, 3, 7 and 21.
18444 is divisible by 3: 18444/3 = 6148. 18444 is not divisible by 5: 18444/5 = 3688.8 18444 is divisible by 6: 18444/6 = 3074 18444 is not divisible by 7: 18444/7 = 2634.857142 18444 is not divisible by 10: 18444/10 = 1844.4
No; 1+7+3+5= 16 16 isn't divisible by 3.
19 divisible by 5, 14 divisible by 7. Of these, 3 divisible by both.
1, 2, 7, 3 and 6 are not divisible by 4 and/or 9. 12736 is divisible by 4 but not by 9.
Yes, 75 is divisible by 3. A number is divisible by 3 if the sum of its digits is also divisible by 3. In this case, 7 + 5 = 12, and 12 is divisible by 3 (12 ÷ 3 = 4), so 75 is divisible by 3.
42 is divisible by 2, 3, 6, & 7
3 is not divisible by 72. 72 is divisible by 3.
