Ah, finding the Highest Common Factor (HCF) is like finding a happy little tree in a forest of numbers. Let's gently explore the factors of 162, 72, and 54. By carefully examining their factors, we can identify the largest number that divides evenly into all three, creating a harmonious blend of numbers.
They are 18, 36, 54, 72, 90, 108, 126, 144 and 162.
Here are the first 10: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180 . . .
1, 2, 3, 6, 9, 18, 27, 54 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
18 and 36 do. So do 18 and 54, 36 and 54, 18 and 72, 54 and 72, and an infinite number of other pairs of numbers.
18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, . . . 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, . . .
18, 36, 54, 72, 90, 108, 126, 144, 162, etc.
18, 36, 54, 72, 90, 108, 126, 144, 162, 180 . . .
The GCF/HCF of 54 and 504 is 18.
18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198 +18 . . .
The HCF of 48 and 72 is 24. The LCM is 144.
The GCF is 18.
