16 is the greatest common factor between 128 and 432.
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 432, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. Examples: The common factors of 8 and 432 are 1, 2, 4, and 8; the greatest common factor is 8. The common factors of 19 and 432 are 1; the greatest common factor is 1. The common factors of 100 and 432 are 1, 2, and 4; the greatest common factor is 4.
The greatest common factor of 432 and 378 is 54
The Greatest Common Divisor of 432, 360 is 72.
The Greatest Common Factor (GCF) of 432 and 588 is 12.
The GCF is 8.
8 is their greatest common factor.
216
432
Since 108 is a factor of 432, it is automatically the GCF.
432
The GCF is 16.
The GCF is 1.
