What is the greatest common factor of 7 and 9?
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.
