What is the greatest common factor of 84 and 99?

Answer: 3Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One 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 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84.The factors of 99 are 1, 3, 9, 11, 33, and 99.The common factors are 1 and 3. Therefore, the greatest common factor is 3.


What is the greatest common factor of 35 and 84?

The greatest common factor (or greatest common divisor) of 35 and 84 is 7.


What is the greatest common factor of 42 72 and 84?

Answer: 6Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.Method:One 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 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84.The common factors are 1, 2, 3, and 6. Therefore, the greatest common factor is 6.


What is the greatest common factor of 70 and 84?

The GCF of 70 and 84 is 14. One way to approach this is to look at the difference between 70 and 84, which is 14. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference. Since both 70 and 84 are divisible by 14, the greatest common factor is 14. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The common factors are 1, 2, 7, and 14. Therefore, the greatest common factor is 14. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 70 are 2, 5, and 7. The prime factors of 84 are 2, 2, 3, and 7. The prime factors in common are 2 and 7, so the greatest common factor is 2 x 7 = 14. 14


What is the greatest common factor of 16 and 84?

One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 16 are 1, 2, 4, 8, and 16. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 84 are 2, 2, 3, and 7. The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.

What are the common factors and greatest common factor of 84?

There cannot be a greatest common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
