If a number is divisible by 4, it also means that the same number is divisible by 2.

But if the number ends in a 3, it can't be divisible by 2 and, to a further extent, can't be divisible by 4.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Explain Why a number which ends in 3 cannot be a multiple of 4?

Check it out: 4,8,12,16,20,24,28,32,36. No threes.


Why a number ends in 3 cannot be multiple of 4?

4 is an even number and so all multiples of 4 must be even. A number ending in 3 is not even and so cannot be a multiple of 4.


Is 3 a multiple of 5?

No.3 is less than 5, thus cannot be a multiple of it; 3 is prime, therefore cannot be a multiple of any number besides 3 (which is one of its factors); by definition, 3 is ismply not a multiple of any number but 1 and 3.


Why can't a number that ends in 3 be a multiple of 4?

A number that ends in 3 can't be a multiple of 4 because the 4 times table goes in a pattern, (e.g 4, 8, 12, 16, 20, 24.) If the number ends in either 0 2 4 6 8 then it couldbe a possible multiple of 4. It always ends in an even number. 3 is not an even number so it is not going to be the last number of a multiple of 4.


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


Why can a number which ends in 3 not be a multiple of 6?

All multiples of 6 are even numbers.


What number is both a prime number and a multiple of 3?

No number that is a multiple of 3, can be a prime number. A prime number must only be divisible by itself and 1. It cannot be divisible by any other number. Therefore if it is a multiple of 3, then it must be divisible by 3 and hence, not a prime number.


Why a number cannot ends in 3 cannot be in the 6 times table?

Since 6 is an even number, its multiples are all even numbers as well. This means that each of its multiples ends in an even number (0, 2, 4, 6, 8). Since 3 is an odd number, any integer ending in a 3 is odd, thus proving that the number is not a multiple of 6. cause 6 is even and any number multiply by an even number is even Obviously any number ending with a 3 is odd 6 = 3 x 2 6 x Z = 3 x 2 x Z so the number is even and therefore cannot ends in 1, 3, 5, 7 or 9

Is 103 a multiple of 3?

I think so. Because it ends in a 3.


What is a rule for deciding whether or not a number is divisible by?

There are different rules for different number 2: ends in 2,4,6,8,0 3: digits add up to multiple of 3 4: last two digits are divisible by 4 5: ends in 5,0 6: follows the rules of both 2 and 3 9: digits add up to a multiple of 9 10: ends in 0


What is the least common multiple of 3 and?

It would help to have that other number. If the other number is a multiple of 3, the LCM is that number. If it is not a multiple of 3, the LCM is 3 times that number.


What is the largest multiple of 3 and 7?

There is no such number. Since if x were the largest multiple of 3 and 7 then what about 2x? 2x would be a multiple of 3 since x is a multiple of 3; 2x would be a multiple of 7 since x is a multiple of 7; and 2x is bigger than x. So x cannot be the largest.


Is 4339 divisible by 3?

No. To find if a number is a factor of 3, add the number's digits. If the resulting number is a multiple of 3, then the original number is a multiple of 3. In 4339, the digits of the number added together is 19, which is not a multiple of 3.


What is the lowest common multiple of 30 and the greatest common factor of 3?

There is no answer. There cannot be a lowest common multiple of a single number, such as 30, because "common multiple" means a multiple that two or more numbers have in common. Likewise, there cannot be a highest common factor of a single number, such as 3, because "common factor" means a factor that two or more numbers have in common.


Is 92 a multiple of 3?

No, 92 is not a multiple of 3. A quick way to check if a number is a multiple of 3 is: add up the digits of the number you are checking; if this sum equals 3 or a multiple of 3, then the number is a multiple of 3. So in this case, 92 --> 9+2=11, which is not a multiple of 3. If you have to you can add again, so for 11 --> 1+1=2, which is not a multiple of 3. You can always repetitively add until you get to a single digit answer: if it's 3,6 or 9 then it's a multiple of 3. Also if your sum is 9 or a multiple of 9, then the original number is a multiple of 9. To check for 6, if a number is a multiple of 3, and also a multiple of 2 (an even number), then the number is a multiple of 6.


Which number is a multiple of 3 and 6?

Any multiple of 6 is a multiple of 3 and 6.


What number is 9 a multiple of?

9 is a multiple of 3. It is 3 x 3.

How do you find out if a number is a multiple of 3?

you add up the digits, and if the sum is a multiple of 3, then the number is divisible by 3!


How do you find out what is divisible by 3?

Add up the digits in the number. If the total is a multiple of 3, the entire number will be a multiple of 3.


What is a number multiplied by 3?

A multiple of 3.


Why a number that ends in a 3 can't be a multiple of 4?

The digit with which a multiple of 4 ends depends on the last digit of the other factor. If the last digit is a zero, the product ends with zero; if the last digit is a 1, the product ends with 4; etc. The only options for the last digit of the product are 0, 2, 4, 6, 8.

How do you work out prime factors of 51?

It doesn't divide by 2 as it's an odd number, its digits add to a multiple of 3 so it divides by 3: 3 x 17. 17 is a prime number so it ends here.
