Answer: 1 The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54. The common factors are 1 and 2; the least (or smallest) common factor is 1.
The least common multiple of the numbers 6, 28 and 77 is 924.
In math terminology, "least" means smallest or lowest. The least common factor is the smallest factor that is common to all the numbers being compared. Look at the results in the following examples.Examples:What is the least common factor of 19 and 24?The factors of 19 are 1 and 19.The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.The only common factor is 1, so the least common factor is 1.What is the least common factor of 30 and 36?The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.The common factors are 1, 2, 3, and 6, so the least common factor is 1.What is the least common factor of 28 and 42?The factors of 28 are 1, 2, 4, 7, 14, and 28.The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The common factors are 1, 2, 7, and 14, so the least common factor is 1.What is the least common factor of 96 and 120?The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96.The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.The common factors are 1, 2, 3, 4, 6, 8, 12, and 24, so the least common factor is 1. As you can see, the smallest factor of two or more numbers is 1.
1 and 2
There are no common factors of 6 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. Thus, there cannot be a least common factor. In general, the least common factor of two numbers is 1.
The factors of 6 are 1, 2, 3, and 6. The factors of 9 are 1, 3, and 9. The common factors of 6 and 9 are 1 and 3. Therefore, the least (smallest) common factor is 1.
The factors of 6 are 1, 2, 3, and 6. The factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors of 6 and 18 are 1, 2, 3, and 6. Therefore, the least common factor (the smallest common factor) is 1.
They are: 1
To find the common factors between two numbers, first list out all of their factors and then choose the ones that they have in common. For example: If your numbers were 36 and 28, you would list out the factors for each: 36| 1, 2, 3, 4, 6, 9, 12, 36 28| 1, 2, 4, 7, 14, 28 The common factors are: 1, 2, & 4
84
Factors of 28 are 1, 2, 4, 7, 14, and 28. Factors of 66 are 1, 2, 3, 6, 11, 22, 33, and 66. The only common factors of 28 and 66 are 1 and 2.
The factors of 6 are 1, 2, 3, and 6. The factors of 8 are 1, 2, 4, and 8. The factors that they have in common are 1 and 2. The least (or lowest) common factor is 1. Note: The least common factor of two or more positive integers will always be 1.
