GCF of 54 and 32 Examples
Example 1: For two numbers, GCF = 2 and LCM = 864. If one number is 54, find the other number.
Solution:
Given: GCF (x, 54) = 2 and LCM (x, 54) = 864
∵ GCF × LCM = 54 × (x)
⇒ x = (GCF × LCM)/54
⇒ x = (2 × 864)/54
⇒ x = 32
Therefore, the other number is 32.Example 2: Find the GCF of 54 and 32, if their LCM is 864.
Solution:
∵ LCM × GCF = 54 × 32
⇒ GCF(54, 32) = (54 × 32)/864 = 2
Therefore, the greatest common factor of 54 and 32 is 2.Example 3: Find the greatest number that divides 54 and 32 exactly.
Solution:
