Question

L.C.M of 72,80 and 252 is what? full sum !
​

Answer 1

Answer:

90720

Step-by-step explanation:

72= 2 X 2 X 2 X 3 X 3

80 = 2 X 2 X 2 X 2 X 5

252 = 2 X 2 X 3 X 3 X 7

If question is asking LCM all together, then we take common from all three and write the remaining.

i.e,

Common = 2 X 2

Number left after separating common = 72 ( 2 X 3 X 3 = 18)

                                                                = 80 ( 2 X 2 X 5 = 20)

                                                               = 252 (3 X 3 X 7 = 63)

So, LCM is = Common X left

= (2 X 2) X 18 X 20 X 63

= 4 X 360 X 63

= 90720
