Finding Greatest Common Factors Made For Math
It's also commonly known as: Web the greatest common factor (gcf) for 21 and 28, notation cgf(21,28), is 7. This calculator only accepts positive integers as input to. In this case, there is only one common prime factor, 7. But there is help available in the form of greatest common factor of 21. Web each of the numbers can be divided by 1, 3, 9, and 27, so you can say that these numbers are common factors of the set of numbers 27, 54, and 81. For 21, 14, and 28 those factors look like this: You can quickly see that the common factor. 1, 2, 7, and 14.
