Question

Find the least number which after being increased by 5 is exactly divisble by 12,24,and36

Answer 1

ANSWER:

• Required number = 67

GIVEN:

• Number = 12,24,36

TO FIND:

• least number which after being increased by 5 is exactly divisble by 12,24,and 36.

SOLUTION:

Firstly we have to find the LCM of 12,24,36

12= 2*2*3

24 = 2*2*2*3

36 = 2*2*3*3

LCM = 2*2*2*3*3

= 72

We have to find a number which after being increased by 5 is exactly divisble by 12,24,and 36 so we have to subtract 5 from the LCM.

Required number = 72-5

= 67

NOTE:

1. This type of question can be solved by first finding the LCM of the given number.
2. Then according to question we will add or subtract the required reminder.
