3, 4, and 7 are the common factors of 9 12 and 21.
The factors of 27 are:1, 3, 9, 27The factors of 63 are:1, 3, 7, 9, 21, 63The Greatest Common Factor:GCF = 9
5, 7, 8, and 9 have no common factors, so the least common multiple is 5×7×8×9=2,520
The common factors of 126 and 162 are: 1, 2, 3, 6, 9, and 18
None. 7 and 9 haveno common factors other than 1.Factors of 7: 1, 7Factors of 9: 1, 3, 9
They have 1 in common.
The factors of 7 are 1 and 7 The factors of 9 are 1, 3, and 9 So the greatest common factor is 1
The factors of 9 are 1, 3 and 9. The factors of 14 are 1, 2. 7 and 14. They have no factors in common except for 1.

Answer:The greatest common factor of 7 and 9 is 1.The common factors of 7 and 9 are only 1.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:The greatest common factor (gcf) of 7 and 9 is 1. This is because 7 is a prime number. Whenever one number is prime, if it is not a factor of the other number, the greatest common factor is 1.Another way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 7 are 1 and 7.The factors of 9 are 1, 3, and 9.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factor of 7 is 7.The prime factors of 9 are 3 and 3.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.1 because factors of 7 are 1,7 and factors of 9 are 1,9,3 and the largest factor they have in common is 1.The GCF is 1.
35 = 5 x 7 63 = 9 x 7 '7' is the only common factor.
The factors of 35 are:1, 5, 7, 35The factors of 63 are:1, 3, 7, 9, 21, 63The common factors are:1, 7

The only common factor is 1.
7 is a prime number, and not a factor of 8 or 9. 1, 2, 4, and 8 are factors of 8. 1, 3, and 9 are factors of 9. 7, 8, and have no common factors. So the least common multiple of 7, 8, and 9 are 7 X 8 X 9, which equals 504504
