One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 65 are 1, 5, 13, and 65. The factors of 213 are 1, 3, 71, and 213. 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 65 are 5 and 13. The prime factors of 213 are 3 and 71. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
Find their greatest common factor, which is 2. Divide both by 2. That gives a ratio of 213 to 3500000.
2 213 is a prime number, that means that no two whole numbers can be multiplied other than 1 and 13 to result in 13. so to answer your question, the only common factor these two numbers have is the number 1.
426 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 8 factors of 426 are 1, 2, 3, 6, 71, 142, 213, and 426.The factor pairs of 426 are 1 x 426, 2 x 213, 3 x 142, and 6 x 71.The proper factors of 426 are 1, 2, 3, 6, 71, 142, and 213 or,if the definition you are using excludes 1, they are 2, 3, 6, 71, 142, and 213.The prime factors of 426 are 2, 3, and 71.The distinct prime factors (listing each prime factor only once) of 426 are also 2, 3, and 71.The prime factorization of 426 is 2 x 3 x 71.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
The positive integer factors of 213 are: 1, 3, 71, 213

Factors of 27: 1, 3, 9, 27Factors of 213: 1, 3, 71, 213GCF (27, 213) = 3
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.
Find their greatest common factor, which is 2. Divide both by 2. That gives a ratio of 213 to 3500000.
There is neither a greatest common factor nor common factors of a single number, such as 1420 because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 1420 are 1, 2, 4, 5, 10, 20, 71, 142, 284, 355, 710, and 1420. The prime factors of 1420 are 2, 2, 5, and 71. Examples: The greatest common factor of 32 and 1420 is 4. The greatest common factor of 213 and 1420 is 71. The greatest common factor of 580 and 1420 is 20.
