The factors of 63 are:
1, 3, 7, 9, 21, 63
The factors of 147 are:
1, 3, 7, 21, 49, 147
The common factors are:
1, 3, 7, 21
The greatest common factor of 63 and 147 is 21.
The Least Common Multiple of 21, 63, 147: 441
The Least Common Multiple (LCM) for 147 63 is 441.
The greatest common factor of 63, 147, and 1764 is 21.
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.
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
The least common multiple of these numbers is 441.
