What is GCF of 24 and 33?
Answer: GCF of 24 and 33 is 3.

Explanation:
The GCF of two non-zero integers, x(24) and y(33), is the greatest positive integer m(3) that divides both x(24) and y(33) without any remainder.
Methods to Find GCF of 24 and 33
The methods to find the GCF of 24 and 33 are explained below.
- Using Euclid's Algorithm
- Prime Factorization Method
- Long Division Method
GCF of 24 and 33 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 = 33 and Y = 24
- GCF(33, 24) = GCF(24, 33 mod 24) = GCF(24, 9)
- GCF(24, 9) = GCF(9, 24 mod 9) = GCF(9, 6)
- GCF(9, 6) = GCF(6, 9 mod 6) = GCF(6, 3)
- GCF(6, 3) = GCF(3, 6 mod 3) = GCF(3, 0)
- GCF(3, 0) = 3 (∵ GCF(X, 0) = |X|, where X ≠ 0)
Therefore, the value of GCF of 24 and 33 is 3.
