Since 27 is not a factor of 279, there is a problem with this problem. But if one of the numbers is 297, the other is 189.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 135 and 189 is 27
The hcf is 12
The GCF is 2.
If you mean 24 and 36 then the HCF is 12
The GCF is 21.
The GCF is 1.
It is 13 because it is the HCF of 325 and 221
You need at least two numbers to find a GCF.
63 is the HCF
I have some options 14,15,19,16,21
The HCF is 1.
441 / 252 = 1 r 189 252 / 189 = 1 r 63 189 / 63 = 3 r 0 The hcf of 441 and 252 is 63
The prime factorization of 189 is 3 x 3 x 3 x 7. You need at least two numbers to find a GCF.
178, 183, 186, 186, 189, 189, 191, 192, 192, 192, 197, 201, 201, 203, 205, 207, 207, 211, 211, 221. There.
189 = 3 x 3 x 3 x 7; 105 = 3 x 5 x 7. Common factors are 3 and 7 so LCM = product /HCF ie 189 x 105/21 = 945
I suggest you learn to use Euclid's algorithm, as the method that is applicable to all sorts of numbers, large and small. Here is the first step:The remainder of the division of 231 by 189 is 42. Therefore, gcf(231, 189) is the same as gcf(189, 42). Continue by dividing 189 by 42, and getting the remainder, etc. (For fairly small numbers, an alternative method is to split each number into prime factors, and check the common prime factors between the two numbers.)
