Find LCM (18,40).

Method 1:

18 = 2 x 3 x 3

40 = 2 x 2 x 2 x 5

GCF (18,40) = 2

LCM(18,40) = (18 x 40)/GCF(18,40)

LCM(18,40) = 720 / 2

LCM(18,40) = 360

Method 2:

40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440, 480, 520, 560, 600

18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270, 288, 306, 324, 342, 360

I would not recommend using this method because it takes so much longer, but if you cannot remember how to do it the other way, use this method.

WhoNiamh thinks of two numbers.The highest common factor of the two numbers is 8.The lowest common multiple of the two numbers is a multiple of 5.What are the two numbers?

To find the two numbers, we need to consider that their highest common factor is 8 and their lowest common multiple is a multiple of 5. The numbers that satisfy these conditions are multiples of 8 and 5. Therefore, the two numbers are 40 and 80, as they have a highest common factor of 8 and a lowest common multiple of 40.
