What is GCF of 52 and 65?
Answer: GCF of 52 and 65 is 13.
Explanation:
The GCF of two non-zero integers, x(52) and y(65), is the greatest positive integer m(13) that divides both x(52) and y(65) without any remainder.
Methods to Find GCF of 52 and 65
The methods to find the GCF of 52 and 65 are explained below.
- Using Euclid's Algorithm
- Prime Factorization Method
- Long Division Method
GCF of 52 and 65 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 = 65 and Y = 52
- GCF(65, 52) = GCF(52, 65 mod 52) = GCF(52, 13)
- GCF(52, 13) = GCF(13, 52 mod 13) = GCF(13, 0)
- GCF(13, 0) = 13 (∵ GCF(X, 0) = |X|, where X ≠ 0)
Therefore, the value of GCF of 52 and 65 is 13.
GCF of 52 and 65 by Prime Factorization
Prime factorization of 52 and 65 is (2 × 2 × 13) and (5 × 13) respectively. As visible, 52 and 65 have only one common prime factor i.e. 13. Hence, the GCF of 52 and 65 is 13.
GCF of 52 and 65 by Long Division
GCF of 52 and 65 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly.
