Answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 147, 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 14 and 147 are 1 and 7; the greatest common factor is 7. The common factors of 147 and 171 are 1 and 3; the greatest common factor is 3.
The greatest common factor of 63, 147, and 1764 is 21.
The GCF is 21.
The greatest common factor of 45 and 63 is 9.
The factors of 63 are:1, 3, 7, 9, 21, 63The factors of 147 are:1, 3, 7, 21, 49, 147The common factors are:1, 3, 7, 21
Factors of 126: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126.Factors of 147: 1, 3, 7, 21, 49, 147.GCF (126, 147) = 21
63 is the HCF
The common factors are: 1, 3 The Greatest Common Factor (GCF) is: 3
3
1
It is 3
factors of 567 = 3x3x3x3x7 factors of 441=3x3x7x7 so common factors among the two numbers are= 3x3x7 so the greatest common factor is =63
