1 is the only common factor.
Just 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.
The factors of 18 are: 1, 2, 3, 6, 9, 18The factors of 63 are: 1, 3, 7, 9, 21, 63The common factors are: 1, 3, 9
The factors of 27 are 1, 3, 9, and 27. The factors of 63 are 1, 3, 9, 7, 21, and 63. The common factors of 27 and 63 are 1, 3, and 9.
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
5, 7, 8, and 9 have no common factors, so the least common multiple is 5×7×8×9=2,520
The factors of 8 are 1, 2, 4, and 8, and the factors of 9 are 1, 3, 9 so the common factor is 1.
The only common factor of 8 and 9 is ' 1 '.
there is no common mutlipe for 7 8 9
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.
Common factors of 72 and 112 are: 1, 2, 4, and 8.
The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56 The factors of 63 are: 1, 3, 7, 9, 21, 63
The factors of 7 are 1 and 7 The factors of 9 are 1, 3, and 9 So the greatest common factor is 1
504 is the least common multiple of 7, 8 and 9. All numbers that are multiples of 504 are multiples of 7, 8 and 9 as well
5, 6, 8, and 9 share no common factors aside from 1.
