β 13y agoThe GCF is 4.
The GCF is 84.
Since 84 is a factor of 504, it is automatically the GCF.
The GCF of 3591 and 84 is 21
The GCF is 84.
gcf is 84
You can calculate this in different ways.You can calculate different multiples of 84, and check each one, to see whether they are also a multiple of 76. This is really only appropriate for fairly small numbers; these numbers are already too large for this method to be convenient.You can separate each number into prime factors. Pick all the common factors. This method is appropriate for medium-sized numbers such as these.You can use Euclid's algorithm. This method is appropriate for numbers of just about any size.Using Euclid's algorithm, you divide 84 by 76. THE REMAINDER IS WHAT REALLY INTERESTS US. In this case, the remainder is 8. Now, applying Euclid's algorithm, gcf(84, 76) = gcf(76, 8). Apply the same procedure again (divide 76 by 8, get the remainder, and use 8 and this remainder), until you have two numbers, one of which is zero. In that case, the gcf is the other number.
If that's 28, 56 and 84, the GCF is 28. If that's 2856 and 84, the GCF is 84.
