In the multiplication sentence 3x5=15, the numbers 3 and 5 are known as factors. Factors are the numbers that are multiplied together to obtain a product. In this case, 3 and 5 are the factors that, when multiplied, result in the product of 15.
Here is one factor tree of 300: 300 20 x 15 (4x5) x (3x5) ((2x2)x5) x (3x5) You have reduced it to prime numbers, so you are finished. The factors of 300 are 2, 2, 3, 5, and 5.
4^3x5^2
4 = 4, and 4 = 2 x 2, so either a single prime number to the power 4-1 (23, 33, etc.), or two different prime numbers, each to the power 2-1, for example, 2x3, 2x5, 3x5, etc.
Any numbers that don't have common prime factors will do; for example, 23 and 32; 2x3 and 5x7, 3x5 and 2x7, etc.Any two consecutive numbers will have no common factor, for example, 8 and 9 (the first example I gave above), or 100 and 101. However, in the second example, 101 is not a composite number.

The generalisation is that multiplication is Abelian (or commutative) for numbers.
Commutivity of multiplication or the commutative property of multiplication.
3x5=15 3 x5
The answer of a multiplication problem ex. 3x5=15 15 would be the product

3 x 7 = 3 x (5 + 2) And since multiplication is distributive over addition, 3 x (5 + 2) = 3 x 5 + 3 x 2
Bob had 3 crates. He had 5 calculus textbooks in each. How many calculus textbooks in all? 15 calculus textbooks.
Multiplication is done before addition, so it will be done before the plus. The result is:35 + 3 x 5 = 50
A product is the result of multiplication, and a sum is the result of addition. Multiplication and addition are alike in that multiplication is really just repeated addition. For example, to multiply 3x5 is the same as 3+3+3+3+3 or 5+5+5. These will all result in either the product of 15 or the sum of 15.
Divide the area of the windows by the area of the sheets. Note: 3x5 and 2x4 are not areas, they are numbers. And you don't say how big the sheets are, so it is difficult to be helpful.
1080 = 2^3x3^3x5 200= 2^3x5^2 LCM (1080,200) = 2^3x3^3x5^2 = 1800
Ah, what a happy little question! The inverse operation of multiplication is division, so to find the inverse of 3x5 equals 15, you would divide 15 by 5 to get 3. Remember, math is like painting a beautiful landscape - just follow the steps with a gentle touch and you'll create something wonderful.
