What are a pair of factors of 20?
1 and 20 are a factor pair of 20 since 1 x 20= 20 2 and 10 are a factor pair of 20 since 2 x 10= 20 4 and 5 are a factor pair of 20 since 4 x 5= 20 5 and 4 are a factor pair of 20 since 5 x 4= 20 10 and 2 are a factor pair of 20 since 10 x 2= 20 20 and 1 are a factor pair of 20 since 20 x 1= 20
What is the greatest common factor of 49 and 70?
One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 49 are 1, 7, and 49.The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70.The common factors are 1 and 7. Therefore, the greatest common factor is 7.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 49 are 7 and 7.The prime factors of 70 are 2, 5, and 7.The common prime factors are a single 7, so the greatest common factor is 7.The GCF is 7.The GCF is: 7
What is the greatest common GCF of 35 and 49?
The factors of 35 are: 1, 5, 7, 35The factors of 49 are: 1, 7, 49The common factors are: 1, 7The Greatest Common Factor (GCF) is: 7
What are the factors and prime factors of 5?
5 is a prime number. The only two factors of a prime number are 1 and itself.The two factors of 5 are 1 and 5. There are only two factors for a prime number.The only factor pair of 5 is 1 x 5. There is only one factor pair for a prime number.The proper factors of 5 are only 1 or,if the definition you are using excludes 1, there are none.The only prime factor of 5 is 5. There is only one prime factor for a prime number - itself.The only distinct prime factor of 5 is also 5, since there is no repetition of factors.The prime factorization of 5 is 5. In some cases, to emphasize that it is prime, you might write the prime factorization as 1 x 5.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.
What is the greatest common factor of 35 42 and 49?
The greatest common factor (GCF) of 35, 42, and 49 is 7. To find the GCF, you need to determine the factors of each number and then identify the largest factor that is common to all three numbers. In this case, the factors of 35 are 1, 5, 7, 35; the factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42; and the factors of 49 are 1, 7, 49. The largest factor that is common to all three numbers is 7, making it the greatest common factor.
