• Check if the number is divisible by all the numbers from start to end

function check_if_divisibly start, end, number

index = start
is_divisible_by_all = True
until index <= end:
    if number%index != 0 then
        is_divisible_by_all = False
        return is_divisible_by_all
    index = index + 1
return True

• using the divisible by all in lcm calculations

start = 1
end = 10
lcm = end
lcm_found = False
until lcm_found == False   # until lcm not found do the operation continuously
    if is_divisible_by_all(start, end, lcm) then
        lcm_found = True
        print lcm
        stop
    lcm = lcm + end

• Problem Refer Here

start = 1
end = 100
index = start
sum = 0
square_sum = 0
until index <= end
    sum = sum + index
    square_sum = square_sum + index * index
    index = index + 1

result = sum * sum - square_sum
print result
