What are the common factors and greatest common factor of 128?
There is neither a greatest common factor nor common factors of a single number, such as 128, 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.
What is the greatest common factor of 128 and 245?
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 128 are 1, 2, 4, 8, 16, 32, 64, and 128. The factors of 245 are 1, 5, 7, 35, 49, and 245. The only common factor is 1. Therefore, the greatest common factor is 1.
Which is not the greatest common factor of 128?
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 of 28 and 128?
Factors of 28: 1 2 4 7 14 28 Factors of 128: 1 2 48 16 32 64 128 The GCF of 28 and 128 is 4
What is the greatest common factor of 144 and 128?
The greatest common factor of 144 , 128 = 16
What is the greatest common factor of 48 and 128?
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 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.The factors of 128 are 1, 2, 4, 8, 16, 32, 64, and 128.The common factors are 1, 2, 4, 8, and 16. Therefore, the greatest common factor is 16.Factors of 48 are 1, 2, 4, 6, 8, 12, 24, and 48Factors of 128 are 1, 2, 4, 8, 16, 32, 64, and 128The GCF of 48 and 128 is 8
What is the greatest common factor of 64 and 128?
The Greatest Common Factor (GCF) of 64 and 128 is: 64
What is the greatest common factor of 128 and 65?
128 and 65 have no common factor other than 1. 2 is the only prime factor of 128. 5 and 13 are the prime factors of 65. 128 times 65 equals 1,320.
What is the greatest common factor of 4880 and 128?
Answer: 16 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 128 are 1, 2, 4, 8, 16, 32, 64, and 128. The factors of 4880 are 1, 2, 4, 5, 8, 10, 16, 20, 40, 61, 80, 122, 244, 305, 488, 610, 976, 1220, 2440, and 4880. The common factors are 1, 2, 4, 8, and 16. Therefore, the greatest common factor is 16. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 128 are 2, 2, 2, 2, 2, 2, and 2. The prime factors of 4880 are 2, 2, 2, 2, 5, and 61. The prime factors in common are 2, 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 x 2 = 16. Another method is to use the Euclidean algorithm. 4880 ÷ 128 = 38 remainder 16 128 ÷ 16 = 8 with no remainder Therefore, since there was no remainder when dividing by 16, the greatest common factor of 128 and 4880 is 16.
What is the greatest common factor of 128 and 1000?
The greatest common factor of 128 and 1000 is 8.
What is the greatest common factor of 75 and 128?
Greatest common factor of 128 and 75 is 1.
What is the gcf of 84 and 128?
The factors of 84 are:1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84The factors of 128 are:1, 2, 4, 8, 16, 32, 64, 128The common factors are:1, 2, 4The Greatest Common Factor (GCF) is:4
