Accumulative Effect

2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder.

What is the smallest number that is evenly divisible by all of the numbers from 1 to 20?

My solution in Ruby:

def has_remainder?(var)
  1.upto(20) { |i| return true if var % i != 0 }
  false
end
 
number = 0
loop do
  number += 1
  break if !has_remainder?(number)
end
puts numbe
