The factors of 91 are:1, 7, 13, 91The factors of 156 are:1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156The common factors are:1, 13
-187
The common factors of 35 and 91 are 1 and 7.
The Greatest Common Factor (GCF) is: 13
13
The common factors of 39 and 91 are: 1 and 13
Answer: 13Definition: 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 39 are 1, 3, 13, and 39.The factors of 91 are 1, 7, 13, and 91.The factors of 130 are 1, 2, 5, 10, 13, 26, 65, and 130.The common factors are 1 and 13. Therefore, the greatest common factor is 13.
13, 26, 39, 52, 65, 78, 91, 104, 117, 130.
The GCF is 13.
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.
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. 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 39 are 1, 3, 13, and 39. The factors of 91 are 1, 7, 13, and 91. The factors of 143 are 1, 11, 13, and 143. The common factors are 1 and 13. Therefore, the greatest common factor is 13.
The factors of 78 are: 1, 2, 3, 6, 13, 26, 39, 78 The factors of 91 are: 1, 7, 13, 91 The factors of 156 are: 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156 The common factors are: 1, 13 The Greatest Common Factor: GCF = 13
The factors of 91 are:1, 7, 13, 91The factors of 156 are:1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156The common factors are:1, 13
Factors of 91: 1, 7, 13, 91Factors of 117: 1, 3, 9, 13, 39, 117GCF (91, 117) = 13
To find the greatest common factor, or GCF, you must first identify the factors for each number.For 91, its factors are 1, 7, 13, and 91.For 78, its factors are 1, 2, 3, 6, 13, 26, 39, and 78.13 is the highest (or greatest) factor they have in common, so the GCF for 91 and 78 is 13.
The first 10 multiples of 13 are: 13, 26, 39, 52, 65, 78, 91, 104, 117, and 130.
The common factors of 63 and 91 are 1 and 7.
