Front

What is the least common multiple (LCM)?

Back

The least common multiple (LCM) of two or more integers is the smallest positive integer that is divisible by each of the integers.

Front

How do you find the LCM of two numbers?

Back

To find the LCM of two numbers, you can list the multiples of each number and find the smallest multiple they have in common, or use the formula: LCM(a, b) = (a * b) / GCF(a, b).

Front

What is the greatest common factor (GCF)?

Back

The greatest common factor (GCF) of two or more integers is the largest positive integer that divides each of the integers without leaving a remainder.

Front

How do you find the GCF of two numbers?

Back

To find the GCF of two numbers, you can list the factors of each number and find the largest factor they have in common, or use the prime factorization method.

Front

What does it mean to express a number in exponential form?

Back

Expressing a number in exponential form means writing it as a base raised to a power, indicating how many times the base is multiplied by itself.

What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), often abbreviated as PEMDAS.

How do you simplify the expression 2g?

Back

The expression 2g is already in its simplest form, representing twice the value of g.

Front

What is the relationship between LCM and GCF?

Back

The relationship between LCM and GCF is given by the formula: LCM(a, b) * GCF(a, b) = a * b.
