The common factors of 30 and 40 are 1, 2, 5, 10
Any number between 30 and 40 can be a factor. The common factors of 30 and 40 are 1, 2, 5 and 10.
The common factors of 30 and 40 are: 1, 2, 5, 10.
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The common factors of 30 and 40 are 1, 2, 5, and 10, and the GCF is 10.
The common factors of 35 and 40 are: 1 and 5
The factors of 40 are 1,2,4,5,8,10,20 and 40. For them to be common, they need to be compared to another set of factors.
Answer:The greatest common factor of 30 and 40 is 10.The common factors of 30 and 40 are 1, 2, 5, and 10.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods: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 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The common factors are 1, 2, 5, and 10. Therefore, the greatest common factor is 10.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 30 are 2, 3, and 5.The prime factors of 40 are 2, 2, 2, and 5.The common prime factors are 2 and 5, so the greatest common factor is 2 x 5 = 10.10
Since 40 is a factor of 120, all of its factors are common.
Since 20 is a factor of 40, all of its factors are common.
Factors of 30 are: 1, 2, 3, 5, 6, 10, 15, and 30. Factors of 40 are: 1, 2, 4, 5, 8, 10, 20, and 40. Find the greatest factor they both have in common. That is the greatest common factor.
The GCF is 5.
It is 10
