What is the greatest common factor of 142 and 231?
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 142 are 1, 2, 71, and 142. The factors of 231 are 1, 3, 7, 11, 21, 33, 77, and 231. 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 factors of 142 are 2 and 71. The prime factors of 231 are 3, 7, and 11. There are no prime factors in common, so the numbers are relatively prime, meaning the greatest common factor is 1.
What is the greatest common factor of 88 and 231?
The factors of 88 are 1, 2, 4, 8, 11, 22, 44, and 88. The factors of 231 are 1, 3, 7, 11, 21, 33, 77, and 231. The common factors are 1 and 11. Therefore, the greatest common factor is 11. The greatest common factor can also be calculated by finding the prime factors and multiplying the common prime factors together. The prime factors of 88 are 2, 2, 2, and 11. The prime factors of 231 are 3, 7, and 11. The common prime factors are a single 11, so 11 is the greatest common factor.
What is the greatest common factor of 231 and 154?
The greatest common factor of 231 and 154 is 77.
What is the greatest common factor of 121 and 231?
The greatest common factor (GCF) of 121 and 231 is 11.
What is the highest common factor of 189 and 147?
Prime factors of 189 are 33 and 7Prime factors of 231 are 3, 7, and 11HCF of 189 and 231 is 7
What would be the common factors for 231?
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.
What is the greatest common factor for 231 and 55?
Factors of 231: 1, 3, 7, 11, 21, 33, 77, 231 Factors of 55: 1, 5, 11, 55 GCF (231, 55) = 11
What are the greatest common factors of 210 and 214?
The GCF of 210 and 231 is 21. The factors of 231 are: 1, 3, 7, 11, 21, 33, 77 and 231 The factors of 210 are: 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105 and 210 The highest common factor is 21
What is the GCF of 105 and 231?
The greatest common factor of 105 and 231 is 21.
What is the greatest common factor of 126 and 231?
21
What is a factor of 210 and 231?
The factors of 231 are 1,3,7,11,21,33,77 and 231 The factors of 210 are 1,2,3,5,6,7,10,14,15,21,30,35,42,70,105 and 210 The common factors are therefore 1,3,7 and 21
What is the greatest common factor of 60 and 231?
GCF(60, 231) = 3.
