Sincevis divisible by 2, 3 and 15,vmust be a multiple of 30. Any number that is divisible by both 2 and 15 must be divisible by their product, 30, since this is the least common multiple.

Out of all the answer choices,v+ 30 is the only one that equals a multiple of 30.

We are given information that m/4 is 10 greater than m/3. We set up an equation where m/4 = m/3 + 10.

We must then give the m variables a common denominator in order to solve for m. Since 3 * 4 = 12, we can use 12 as our denominator for both m variables.

m/4 = m/3 + 10 (Multiply m/4 by 3 in the numerator and denominator.)

3m/12 = m/3 + 10 (Multiply m/3 by 4 in the numerator and denominator.)

3m/12 = 4m/12 + 10 (Subtract 4m/12 on both sides.)

-m/12 = 10 (Multiply both sides by -12.)

m = -120

120/4 = -30和120/3 = -40。-30是10克reater than -40.

The greatest common divisor ofandis 10. This means that the prime factorizations ofandmust both contain a 2 and a 5.

The greatest common divisor ofandis 9. This means that the prime factorizations ofandmust both contain two 3's.

The greatest common divisor ofandis 8. This means that the prime factorizations ofandmust both contain three 2's.

Thus:

最大的共同因素是一种常见的因素y two or more numbers. Both numbers are even, so let's divide both numbers by two. We get. These are prime numbers (factors of one and itsef) in which we are done. Anytime we have two prime numbers or one prime and one composite number, we are finished. So the greatest common factor is.

最大的共同因素是一种常见的因素y two or more numbers. Both numbers are even, so let's divide two for both numbers. We get. We have one prime and one composite number, so we are finished. The greatest common factor is.

最大的共同因素是一种常见的因素y two or more numbers. If you know the divisibility rule of(sum of digits are divisible by), then the answer is justas the quotient is. We have a prime and composite number. However, if you don't and only know the divisibility rule of, then we can divide both numbers byto get. We do it once more to get. Since we divided twice by, we multiply these factors and this is our greatest common factor of. Our answer is.

最大的共同因素是一种常见的因素y two or more numbers. If you know divisibility rule of, then this is the answer. However, this isn't easy to spot, so we will do process of elimination. The numbers are odd and if we have even factors, we never generate odd numbers sois wrong. Next, check divisibility rule of. The digits ofadd towhich isn't divisible bysois wrong. Next, let's divideinto. We get a decimal value and that's wrong since if we considerto be a multiple of, it should be a whole number and not a decimal. Finally, by dividingand, it's also. This is our answer. To find out ifis divisible by, just add the outside digits and match the middle one. Since it does,is divisible by.

These two numbers are definitely divisible by. When we divide both numbers by, we getandremaining. Since we have a combination of a prime and composite number, then we can't find any more factors. Our answer is.
