What is a LCM?Lowest Common Multiple.
I can recognise multiples and find lowest common multiples.
The multiples of 6 are:6, 12, 18, 24, 30.
The multiples of 4 are:4, 8, 12, 16, 20, 24, 28, 32.
The lowest multiple in both lists is ... 12The LCM of 4 and 6 is 12
I can recognise multiples and find lowest common multiples.
The multiples of 12 are:12, 24, 36, 48,
The multiples of 3 are:3, 6, 9, 12,
The lowest multiple in both lists is ... 12The LCM of 3 and 12 is 12
I can recognise multiples and find lowest common multiples.
