Group 2 of LS2 have been learning and some revising on “Lowest Common Multiples” (LCM).
LCM consists of multiplication where you find the number in common between 2 numbers multiplication order. For an example you could use 4 and 7 up to 5 to find the LCM. You times both up to 5 and if there is the same number diagonal from eachother. (4, 8, 12, 16, 20.) and (7, 14, 21, 28, 35) in this case, there is no common multiple up to five. But if you know your four times tables if you add 2 on you can make it to 28, which the 7 times table has making it the answer.
