first find the numbers with the factors of: 2,3,4,5,6,7 find the minum if something has a factor of 6 then it also has a factor of 3 and 2 so just multiply by the lcm of all of them which is found by 2=2 3=3 4=2 times 2 5=5 6=2 times 3 7=7
LCM=2 times 2 times 3 times 5 times 7=420
now divide 100000 by 420 and round down 100000/420=238.095=238.1 round doen 238
