I don't even know if something like this is possible, but:
Let us say we have three numbers:
A = 6
B = 7.5
C = 24
I would like to find a few evenly spaced common multiples of these numbers between 0 and 2. So the requirement is: one_of_these_numbers / common_multiple = an_integer (or almost an integer with a particular tolerance)
For example, a good result would be [0.1 , 0.5 , 1 , 1.5]
I have no idea if this is possible, because one can not iterate through a range of floats, but is there a smart way to do it?
I am using python, but a solution could be represented in any language of your preference.
Thank you for your help!
While I was writing my question, I actually came up with an idea for the solution.
To find common divisors using code, we have to work with integers.
My solution is to multiply all numbers by a factor = 1, 10, 100, ... so that we can act as if they are integers, find their integer common divisors, and then redivide them by the factor to get a result.
Better explained in code:
a = 6
b = 7.5
c = 24
# Find a few possible divisors between 0 and 2 so that all numbers are divisible
by div.
# We define a function that finds all divisors in a range of numbers, supposing
all numbers are integers.
def find_common_divisors(numbers, range_start, range_end):
results = []
for i in range(range_start + 1, range_end + 1):
if all([e % i == 0 for e in numbers]):
results.append(i)
return results
def main():
nums = [a, b, c]
range_start = 0
range_end = 2
factor = 1
results = [1]
while factor < 11:
nums_i = [e * factor for e in nums]
range_end_i = range_end * factor
results += [e / factor for e in find_common_divisors(nums_i, range_start, range_end_i)]
factor *= 10
print(sorted(set(results)))
if __name__ == '__main__':
main()
For these particular numbers, I get the output:
[0.1, 0.3, 0.5, 1, 1.5]
If we need more results, we can adjust while factor < 11:
to a higher number than 11 like 101.
I am curious to see if I made any mistake in my code. Happy to hear some feedback.
Thank you!
