What are the highest common factor of 22 and 58?

Answer 1

The greatest common factor (or the highest common factor) is the highest number that divides exactly into two or more numbers.

22: 1, 2, 11, 22

58: 1, 2, 29, 58

The highest common factor of 22 and 58 is 2.

Answer 2

The highest common factor (HCF) of 22 and 58 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, you can use methods like prime factorization or the Euclidean algorithm. In this case, the prime factorization of 22 is 2 x 11 and the prime factorization of 58 is 2 x 29. The common factor between them is 2, so the HCF of 22 and 58 is 2.
