Factors of 49 are 1, 7, and 49.Factors of 84 are 1, 2, 3, 4, 7, 12, 21, 28, 42, and 84.Factors of 98 are 1, 2, 7, 14, 49, and 98.Their greatest common factor is 7.

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.

Answer: 14Definition: 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 14 are 1, 2, 7, and 14.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 and 14. Therefore, the greatest common factor is 14.The factors of 14 are:1, 2, 7, 14The factors of 84 are:1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84The common factors are:1, 2, 7, 14The Greatest Common Factor (GCF) is:14Since 14 is a factor of 84, it is automatically the GCF.
