Can you always find the least common multiple of two numbers by multiplying them together.why or why not?
You can always find a common multiple of two numbers by multiplying them together; it will not always be the least common multiple. As one counterexample, if one of the numbers is a multiple of the other, the first number is the LCM of the two.
9 x 3 = 27
The LCM of 9 and 3 is 9.
4 x 6 = 24
The LCM of 4 and 6 is 12.
What else can I help you with?
When you multiply a negative number by a negative number is the number positive or negative?
Positive A simple rule to remember this is when multiplying two numbers with the same sign, the result is ALWAYS positive. When multiplying two numbers with different signs, the results is ALWAYS negative.
Is the least common multiple of two numbers always divisible by the greatest common factor of the two numbers?
Yes, the least common multiple of two numbers is always divisible by those numbers' greatest common factor.
Do two whole numbers always have a least common multiple?
Yes. If A and B are any two whole numbers then A*B is a common multiple. Then either A*B is the least common multiple of A and B or one of its factors is.
Is the LCM of two numbers the product of the two numbers explain in words?
Not always. The product of two numbers will always be a common multiple, but it will not always be least. The product of 4 and 9 is 36. The LCM of 4 and 9 is 36. The product of 4 and 8 is 32. The LCM of 4 and 8 is 16.
If multiplying 2 prime numbers will the product always be prime?
If you multiply 2 prime numbers. the result will never be prime. A prime number is one that has no factors except itself and one. The number specified in the question has as factors the 2 prime numbers cited.
Is it true you can always find a common multiple of a pair of numbers by multiplying them together?
No you can't, but sometimes you can.
Can you always find the least common multiple of 2 numbers by multiplying them together?
No, that will not always work. in the case for some numbers it will work. for example 3 * 4 = 12. it works here. however if you do that for 30 and 20, you will get 600. the real lowest common multiple is 60. so it does not always work.
Can you always find the LCM for two numbers by multiplying them Why or why not?
This does not work when one of the numbers is negative.
Do two natural numbers always have a least common multiple?
Yes, two natural numbers always have a least common multiple.
Is the product always the least common multiple of the numbers?
No, only if the numbers are relatively prime.
What are the common multiples of four and seven?
28, 56, 84 you can always find a common multiple of two numbers by multiplying them (but that won't always be the least common multiple)... the other common multiples can b found by multiplying that number with any other positive integer... for example, if you have two numbers (a and b), then one of their common multiples is a x b (but not always the smallest one), and the others are 2 x a x b, or any other positive integer times a x b
Do multiples and product mean the same?
No, multiples and product do not mean the same thing. Multiples are the result of multiplying a number by an integer, resulting in a sequence of numbers that are all divisible by the original number. The product, on the other hand, is the result of multiplying two or more numbers together. In simpler terms, multiples are the numbers in the times table of a given number, while the product is the result of multiplying numbers.
Do always need to regroup when you are multiplying digit or digit numbers?
No. It depends on how good you are at arithmetic.
What is 51 X 5?
The product of 51 multiplied by 5 is 255. This can be calculated by multiplying the two numbers together: 51 x 5 = 255. The result is a multiple of 5, as any number multiplied by 5 will always result in a multiple of 5.
When you multiply a negative number by a negative number is the number positive or negative?
Positive A simple rule to remember this is when multiplying two numbers with the same sign, the result is ALWAYS positive. When multiplying two numbers with different signs, the results is ALWAYS negative.
Is the product of two whole numbers always a common multiple of he numbers?
yes
Is the least common multiple of two numbers always divisible by the greatest common factor of the two numbers?
Yes, the least common multiple of two numbers is always divisible by those numbers' greatest common factor.
