GCF of 33 and 36 by Long Division

GCF of 33 and 36 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly.

Step 1: Divide 36 (larger number) by 33 (smaller number).
Step 2: Since the remainder ≠ 0, we will divide the divisor of step 1 (33) by the remainder (3).
Step 3: Repeat this process until the remainder = 0.

The corresponding divisor (3) is the GCF of 33 and 36.

GCF of 33 and 36 Examples

Example 1: Find the GCF of 33 and 36, if their LCM is 396.

Solution:

∵ LCM × GCF = 33 × 36
⇒ GCF(33, 36) = (33 × 36)/396 = 3
Therefore, the greatest common factor of 33 and 36 is 3.
Example 2: For two numbers, GCF = 3 and LCM = 396. If one number is 36, find the other number.

Solution:

Given: GCF (x, 36) = 3 and LCM (x, 36) = 396
∵ GCF × LCM = 36 × (x)
⇒ x = (GCF × LCM)/36
⇒ x = (3 × 396)/36
⇒ x = 33
Therefore, the other number is 33.
Example 3: Find the greatest number that divides 33 and 36 exactly.

Solution:

The greatest number that divides 33 and 36 exactly is their greatest common factor, i.e. GCF of 33 and 36.
⇒ Factors of 33 and 36:
- Factors of 33 = 1, 3, 11, 33
- Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36
