"Common factor" means a number that is a factor of 23 and also a factor of some other number.
A characteristic can't be "common" to only one case.
The highest common factor of 69 and 92 is 23
7The highest common factor is 7
The G.C.F of 23 and 56 is 1 because 23 is a prime number and neither one of the two factors of 23 are also factors of 56 so therefore the only number that is a factor of 23 and 56 is 1 because it is the only and therefore the highest common factor of 23 and 56. Thank you.
An easy way to find simplest form is to divide each part of the fraction by a common factor until there is no more common factor (that is till they don't share a factor) (for quickest results use the Highest Common Factor). In this case the highest common factor (and the only common factor (barring 1 which will not achieve anything)) is 2. 46/2 = 23 200/2 = 100 There are no more common factors so the simplest form is: 23/100
The highest common factor for 18 and 16 is 2.
