1440 is the answer of the following

this question answer 1440 is the best answer of the following question

LCM of all numbers 15 , 20 , 24 , 32 , 36 is 1440

The least no. is 1440

Hi ,

To find least number which is

divisible by 15 , 20 , 24 , 32 , 36

we have find the LCM of given

numbers.

2| 15 , 20 , 24 , 32 , 36____________________2| 15 , 10 , 12 , 16 , 18_____________________2| 15 , 5 , 6 , 8 , 9___________________3| 15 , 5 , 3, 4, 9___________________5 |5 , 5 , 1 , 4 , 3_______________** |1 , 1 , 1 , 4 , 3______________

Therefore ,

LCM = 2 × 2 × 2 × 3 × 5 × 4 × 3

= 1440

Required least number is 1440.

I hope this helps you.

Hiii friend,

Prime factorisation of 15 = 3 × 5

Prime factorisation of 20 = 2 × 2 × 5

Prime factorisation of 24 = 2 × 2 × 2 × 3

Prime factorisation of 32 = 2 × 2 × 2 × 2 × 2

Prime factorisation of 36 = 2 × 2 × 3 × 3

LCM of 15,20,24,32 and 36 = 2 × 2 × 2 × 3 × 3 × 4 × 5 = 1440.

Hence,

The required Number = LCM(15,20,24,32,36) = 1440.

HOPE IT WILL HELP YOU...... :-)

1440 is the best answer

a) Roban's mother is 26 years older than him. The prodact of their ages (in years3 years from now will be 160. We would like to find Rohan's present age.

Answer»

Let the age of Rohan be “ x ”Then Age of Rohan's mother = x+26

After three years their ages are (x+3),(x+29) respectively .

According to the question ;

( x +3) (x+29) =360

x²+(3+29)x+87=360

x²+32x-273=0

x²+39x-7x-273=0

x(x+39)-7(x+39)=0

(x+39)(x-7)=0

x = 7 or -39

As Age can never be negative we have x =7.

Therefore ,Present age of Rohan =7 years.

830.

ii) Rohan's mother is 26 years older than him. The product of their ages (in years)3 years from now will be 360. We would like to find Rohan's present age.

Answer»

Let the age of rohan be xrohan's mother=x+26after 3 years,(x+26+3) (x+3)=(x+29)(x+3)=x²+3x+29x+87=360=x²+32x=273x(x+32)-273=0solve it x=7,mother's age=7+26=33
