# How can GCF be used in real life?

We can use it for simplifying fractions or ratios!

With fractions, we frequently utilize greatest common factors (GCF), which is quite helpful because fractions are used frequently in daily life.

An effective way to simplify a fraction or ratio is to find the GCF of the denominator and numerator.

To put this into context, let's say you are aware that you need 15 sandwiches for every 5 guests at a party. Since the product of these two numbers is 5, you will need:

Last but not least, math can be very helpful when it comes to recipes!

The following are the proportions for ten cupcakes based on the size of the serving: 100g flour = 10 people: 100g = 1:10; 80g sugar = 10 people: 80g = 1:8; 50g butter = 10 people: 50g = 1:5; and 2 eggs = 10 people: 2 eggs = 1:0.2 eggs.

Thus, you can simply multiply this ratio if you want to make cakes for all of your friends and need 25 cupcakes (what a famous mathematician!).

80g sugar = 1:8 = 1:200; 50g butter = 1:5 = 25:125; 2 eggs = 1:0.2 eggs = 25:5; flour = 1:10 = 25:250.

Let me know if there is anything else I can do. I hope this helps.

The greatest common factor (GCF) can be used in real life situations such as:

- Simplifying Fractions: GCF helps in reducing fractions to their simplest form, which is useful in various mathematical calculations and real-world applications.
- Distributing Resources: In business or economics, GCF can be used to distribute resources or goods among multiple parties efficiently by finding the largest quantity that can be evenly divided among them.
- Planning Events: When planning events or activities involving groups of people, GCF can help determine the least common multiple (LCM) of time intervals, ensuring synchronization and coordination.
- Designing Patterns: GCF is utilized in designing patterns or arrangements of objects, tiles, or motifs, ensuring uniformity and efficiency in design.
- Engineering and Construction: GCF is used in engineering and construction to find the largest common dimensions or factors among various components, optimizing material usage and structural integrity.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
