GCF of 16 and 26 by Listing Common Factors
- Factors of 16: 1, 2, 4, 8, 16
- Factors of 26: 1, 2, 13, 26
There are 2 common factors of 16 and 26, that are 1 and 2. Therefore, the greatest common factor of 16 and 26 is 2.
GCF of 16 and 26 by Euclidean Algorithm
As per the Euclidean Algorithm, GCF(X, Y) = GCF(Y, X mod Y)
where X > Y and mod is the modulo operator.
Here X = 26 and Y = 16
- GCF(26, 16) = GCF(16, 26 mod 16) = GCF(16, 10)
- GCF(16, 10) = GCF(10, 16 mod 10) = GCF(10, 6)
- GCF(10, 6) = GCF(6, 10 mod 6) = GCF(6, 4)
- GCF(6, 4) = GCF(4, 6 mod 4) = GCF(4, 2)
- GCF(4, 2) = GCF(2, 4 mod 2) = GCF(2, 0)
- GCF(2, 0) = 2 (∵ GCF(X, 0) = |X|, where X ≠ 0)
Therefore, the value of GCF of 16 and 26 is 2.
GCF of 16 and 26 by Long Division
GCF of 16 and 26 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly.
- Step 1: Divide 26 (larger number) by 16 (smaller number).
- Step 2: Since the remainder ≠ 0, we will divide the divisor of step 1 (16) by the remainder (10).
- Step 3: Repeat this process until the remainder = 0.
The corresponding divisor (2) is the GCF of 16 and 26.

Solution:
Given: GCF (z, 16) = 2 and LCM (z, 16) = 208
∵ GCF × LCM = 16 × (z)
⇒ z = (GCF × LCM)/16
⇒ z = (2 × 208)/16
⇒ z = 26
Therefore, the other number is 26. -
