You can't have an LCF with only one argument.
The smallest factor (not common factor, there is nothing to compare to), is 1.
The least common factor of any set of numbers is 1.
The least common factor of any set of integers is 1.
The factors of 9 are 1, 3, and 9. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The common factors of 9 and 36 are 1, 3, and 9. Therefore, the least (smallest) common factor is 1.
Common factors of 36, 72, and 90 are: 1, 2, 3, 6, 9, and 18.
It is 1 but the HCF is 12
1, 2, 3, 4
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 of 30 and 36 are 1, 2, 3, and 6. Therefore, the least common factor (the smallest common factor) is 1.
The least common multiple of 25 and 36 is 900. To find the least common multiple you first need to break the numbers down into their prime factors: 25 = 5x5 36 = 2x2x3x3 The next step would be to identify any common factors. In this case there are none. Thus we just multiply all the prime factors together to find the LCM: 2x2x3x3x5x5 = 900 Thus the least common multiple of 25 and 36 is 900.
You need at least two numbers to find a GCF. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36. For them to be common, they need to be compared to another set of factors.
You need at least two numbers to find a GCF.
That's not really how that works. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36 Any time you're looking for the least or greatest common, you're comparing one set of factors to at least one other to see if they have anything in common.
The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 21 are 1, 3, 7, and 21. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors they have in common are 1 and 3. So, the least (or lowest) common factor is 1. Note: The least common factor of two or more positive integers will always be 1.
