The GCF is 7.
The greatest common factor is 9
Otherwise known as greatest common factor, it is 63.
factors of 567 = 3x3x3x3x7 factors of 441=3x3x7x7 so common factors among the two numbers are= 3x3x7 so the greatest common factor is =63
You need at least two numbers to find something in common.
The GCF of 56 and 52 is 4.
The numbers are co-prime so the only common factor is 1.
A mathemtical trick is to note that all three numbers are divisible by '9'. How do we known this?? Because the sum of the digits in each number adds to '9'. Hence 189, 567, 2187) 189 ; 1 + 8 + 9 = 18 = 1 + 8 = 9 567 ; 5 + 6 + 7 = 18 = 1 + 8 = 9 2187 [ 2 + 1 + 8 + 7 = 18 = 1 + 8 = 9 189/9 = 21 567/ 9 = 63 2187/9 = 243 All three sub-answer will divide by '3' Hence 7,9,81 ( There are NO common factors ) Hence 9 x 3 = 27 is the GCF. NB THis mathemtical 'trick' can only be done with '9'. !!!!!
1 and 567 are a factor pair of 567 since 1 x 567= 567 3 and 189 are a factor pair of 567 since 3 x 189= 567 7 and 81 are a factor pair of 567 since 7 x 81= 567 9 and 63 are a factor pair of 567 since 9 x 63= 567 21 and 27 are a factor pair of 567 since 21 x 27= 567
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 81, 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. The factors of 81 are 1, 3, 9, 27, and 81. Examples: The common factors of 18 and 81 are 1, 3, and 9; the greatest common factor is 9. The common factors of 20 and 81 are only 1; the greatest common factor is 1. The common factors of 39 and 81 are 1 and 3; the greatest common factor is 3. The common factors of 81 and 243 are 1, 3, 9, 27, and 81; the greatest common factor is 81.
The factors of 540 are: 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540The factors of 567 are: 1, 3, 7, 9, 21, 27, 63, 81, 189, 567The common factors are: 1, 3, 9, 27The Greatest Common Factor (GCF) is: 27
The common positive integer factors of 28 and 567 are 1 and 7.
1, 3, 7, 9, 21, 27, 63, 81, 189, 567
