Question

The LCM of 8,9and25 With factorisation method

Answer 1

Answer:

$8 = 2 \times 2 \times 2 \\ 9 = 3 \times 3 \\ 25 = 5 \times 5$

Answer 2

Given :

• 8 , 9 and 25

To find :

• LCM

Solution :

first we write the factor each of given numbers

8 = 2 x 2 x 2

= 2³

9 = 3 x 3

= 3²

25 = 5 x 5

= 5²

LCM = 2³ x 3² x 5²

LCM = 8 x 9 x 25

∴ LCM = 1800

Some other formula's :

=> s is the length of the side.

Cube

• V=s³

=> A is the area of the base, h is the height.

Pyramid or Cone

• V=⅓Ah

=> A is the area of the base, h is the height.

Sphere

• V=4/3πr³.
