Question

Find the sum of all integers divisible by 3 and 4 till 100​

Answer 1

Step-by-step explanation:

For the number 3 there are 33 numbers divisible by 3 from 1 to 100.

99/3 = 33

The number 4 has 25 numbers divisible by 4 from 1 to 100

100/4 = 25

If you want the number divisible by both 3 and 4 it is 58 .

If you want the numbers only divisible by 3 or 4 but not both subtract the multiples of 12 which is the LCM ( least common multiple )

100/12 = 8 .333 or approximately 8.

58 - 8 = 50 numbers by 3 or 4 .
