<h3>What is meant by the greatest common factor?</h3>
- The most common factor in mathematics is the highest number that may divide evenly into two other numbers.
- The largest factor that splits both numbers is the greatest common factor. List the prime factors of each integer before calculating the greatest common factor. One 2 and one 3 are shared by those aged 18 and 24. We multiply them to obtain the GCF. Therefore the GCF for 18 and 24 is 2 * 3 = 6.
- The biggest positive integer that divides evenly into all the numbers with no remainder is the greatest common factor (GCF, GCD, or HCF) of a collection of whole numbers.

Answer:
90 people
Step-by-step explanation:
Total: $775
DJ: $250
Cake: $75
Unknown party guests each getting $5
Let the unknown be x
We can form an equation; <em>DJ + Cake + x number of party guests = $775</em>
<em>250 + 75 + 5x = 775</em>
<em>325 + 5x = 775</em>
Subtract 325 from <u>both sides of the equals sign</u>.
<em>5x = 450</em>
Make <em>x</em> the subject and divide both sides by 5
<em>x = 90</em>
There were 90 party guests.
