Which numbers are multiples of 6?
There are an infinite number of multiples of 6 (numbers that six can divide into evenly with no remainder). Without using a calculator, you can determine if a number is a multiple of 6. To be a multiple of 6, it must have both 3 and 2 as factors. So if the number is even, then 2 is a factor. To determine if it is even, look at the ones digit, and if it is (0,2,4,6, or 8) then it's even. Then to determine if 3 is a factor, add the digits in the number, if this sum is a multiple of 3, then the number is also a multiple of 3 (or you could say 3 is a factor). If both of these are true, then the number is a multiple of 6. Example: 984: Last digit (ones digit) is 4, so it's even. Sum 9+8+4=21, which is a multiple of 3, so the number is a multiple of 3. Therefore it is a multiple of 6.

Why is it important to know the math divisibility rules?
Probably because it saves you time. These are the rules from 1 to 50 1: Every number is a multiple of 1 2: The number ends in 0, 2, 4, 6 or 8 (an even digit) 3: The sum of the digits is a multiple of 3 4: The number ends in 00, 04, 08, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92 or 96 5: The number ends in 0 or 5 6: The number is a multiple of both 2 and 3 7: The difference between twice the last digit and the rest of the number is a multiple of 7 8: The 100s digit is even and the last 2 digits are 00, 08, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88 or 96, or the 100s digit is odd and the last 2 digits are 04, 12, 20, 28, 36, 44, 52, 60, 68, 76, 84 or 92 9: The sum of the digits is a multiple of 9 10: The number ends in 0 11: The difference between the last digit and the rest of the number is a multiple of 11 12: The number is a multiple of both 3 and 4 13: The sum of 4 times the last digit and the rest of the number is a multiple of 13 14: The number is a multiple of both 2 and 7 15: The number is a multiple of both 3 and 5 16: The 1000s digit is even and the last 3 digits are a multiple of 16 or the 1000s digit is odd and the last 3 digits are 8 times an odd number 17: The difference between 5 times the last digit and the rest of the number is a multiple of 17 18: The number is a multiple of both 2 and 9 19: The sum of twice the last digit and the rest of the number is a multiple of 19 20: The number ends in 00, 20, 40, 60 or 80 21: The difference between twice the last digit and the rest of the number is a multiple of 21 22: The number is a multiple of both 2 and 11 23: The sum of 7 times the last digit and the rest of the number is a multiple of 23 24: The number is a multiple of both 3 and 8 25: The number ends in 00, 25, 50 or 75 26: The number is a multiple of both 2 and 13 27: The difference between 8 times the last digit and the rest of the number is a multiple of 27 28: The number is a multiple of both 4 and 7 29: The sum of 3 times the last digit and the rest of the number is a multiple of 29 30: The number is a multiple of both 3 and 10 31: The difference between 3 times the last digit and the rest of the number is a multiple of 31 32: The 10000s digit is even and the last 4 digits are a multiple of 32 or the 10000s digit is odd and the last 4 digits are 16 times an odd number 33: The sum of 10 times the last digit and the rest of the number is a multiple of 33 34: The number is a multiple of both 2 and 17 35: The number is a multiple of both 5 and 7 36: The number is a multiple of both 4 and 9 37: The difference between 11 times the last digit and the rest of the number is a multiple of 37 38: The number is a multiple of both 2 and 19 39: The sum of 4 times the last digit and the rest of the number is a multiple of 39 40: The number ends in 000, 040, 080, 120, 160, 200, 240, 280, 320, 360, 400, 440, 480, 520, 560, 600, 640, 680, 720, 760, 800, 840, 880, 920 or 960 41: The difference between 4 times the last digit and the rest of the number is a multiple of 41 42: The number is a multiple of both 2 and 21 43: The sum of 13 times the last digit and the rest of the number is a multiple of 43 44: The number is a multiple of both 4 and 11 45: The number is a multiple of both 5 and 9 46: The number is a multiple of both 2 and 23 47: The difference between 14 times the last digit and the rest of the number is a multiple of 47 48: The number is a multiple of both 3 and 16 49: The sum of 5 times the last digit and the rest of the number is a multiple of 49 50: The number ends in 00 or 50
What is the sum of the product of the first 5 digit number and 5 digit multiple of 6?
The question is a bit ambiguous: "the sum of the product ... " does not seem to make sense. The first 5 digit number is 10000 the first 5 digit multiple of 6 is 10002 Their product is 100020000. I am not sure what to sum, though.
How do you decide if a two digit number is a multiple of a one-digit number?
If the number is even, it is a multiple of 2 If the sum of the digits make a number divisible by 3, the number is a multiple of 3 If the number ends in 5 or 0, the number is a multiple of 5 If the number is divisible by 2 and 3, the number is a multiple of 6 If the sum of the digits make a number divisible by 9, the number is a multiple of 9
What two-digit prime number has the sum of its digits that is not 7 but is a multiple of 7?
No two digit prime number exists that is a multiple of 7. All two digit numbers that are multiples of 7 are compositenumbers.
How can you check if a number is a multiple of 4?
Add the last digit (units digit) to twice the previous digit (tens digit). If this sum is divisible by 4, so is the original number.
