A factor is a divisor - a number that will evenly divide into another number. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 3 are 1 and 3. The factors of 4 are 1, 2, and 4. The only common factor is 1.
Answer:The common factors of 16 and 28 are 1, 2, and 4.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common.Methods:One way to determine the common factors is to find all the factors of the numbers and compare them.The factors of 16 are 1, 2, 4, 8, and 16.The factors of 28 are 1, 2, 4, 7, 14, and 28.The common factors are 1, 2, and 4.
The GCF of 28 and 48 is 4. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4. The GCF of 28 and 48 is 4.
48 = 2^4 × 3^1 5 x 2 = 10 48 has ten factors. The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The factors that change the reaction rates of chemical reactions are: 1)temperature 2)concentration 3)pressure 4)physical state 5)a catalyst

The indicators of a chemical reaction are :- 1. Change in colour 2. Change in temperature 3. Evolution of a gas 4. Formation of a precipitate
There are 4 evidences of a chemical reaction : -Change of colour. -Formation of precipitate. -Release of energy. -Effervescence.
To have common factors, you need at least two numbers to compare, so you can determine what factors they have in common. The factors of 8 are 1, 2, 4, and 8.
A chemical equation can be used to describe a chemical change. For instance when iron combines with oxygen to form iron (III) oxide (rust), a chemical change has occurred. It can be written as a chemical formula: 4 Fe + 3 O2 --> 2 Fe2O3
When a substance changes phase, this is a physical changerather than a chemical change. When water freezes to become ice, or when ice melts to become water, its all physical.

Some factors are: low temperature, low pressure, low concentration of reactants, no stirring, coarse particles, etc.
