📘Key Concepts

GCF
Greatest Common Factor
The largest number that divides two or more numbers evenly with no remainder.
LCM
Least Common Multiple
The smallest non-zero number that is a multiple of two or more numbers.
Distributive Property Connection
36 + 24 = 12(3 + 2)
The GCF is factored out
GCF(36, 24) = 12  ·  Factor pairs: (3, 2)

🔢Find the GCF

GCF(18, 24) =
GCF(30, 45) =
GCF(16, 28) =

🔗Find the LCM

LCM(4, 6) =
LCM(5, 8) =
LCM(6, 9) =

➗Factor Using the GCF

Type the GCF — the number factored out front.

20 + 30 = ?( __ + __ )
14 + 21 = ?( __ + __ )

🌍Real-World Problem

Two machines on the factory floor blink lights at different rates.

🔴 Machine A blinks every 6 seconds
🔵 Machine B blinks every 8 seconds

If both blink at the same moment, how many seconds until they blink together again?

Next shared blink (seconds) =

⚡Challenge

You have 24 red tiles and 36 blue tiles.

You want to arrange all tiles into identical groups — each group has the same number of red and the same number of blue tiles, with no tiles left over.

What is the greatest number of groups you can make?

Greatest number of groups =
