The common factors are: 1, 3
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.
The common factors of 28 and 84 are 1,2,4,7,14 and 28
The common factors of 28 and 84 are 1,2,4,7,14 and 28.
Common factors of 15 and 84 are: 1 and 3.
The greatest common factor (GCF) of 84 and 99 is 3.
The common factors of 21 42 and 84 are 21
Since 12 is a factor of 84, all of its factors are common.
Since 21 is a factor of 84, all of its factors are common.
The factors of 84 are 1,2,3,4,6,7,12,14,21,28,42 and 84. To find a greatest common factor, you need to compare them to another number's factors.
The common factors of 55 and 99 are: 1 and 11
The common factors of 63 and 84 are: 1, 3, 7, and 21
The common factors of 78 and 84 are 1, 2, 3 and 6.
