Question

Find the smallest 4 digit number that can be divided by 22 .36 and 42

Answer 1

Answer:

2772

Step-by-step explanation:

First, find the ICM lowest common multiple of the numbers by factorizing them

2

$2| 22 36 42 \\ 2| 111821 \\ 3| 11921 \\ 3| 1137 \\ 7| 1117 \\ 11| 1111$

Then multiply all the factors i . e all the numbers on the left 2×2×3×3×7×11 = 2772.

since this all already a four digit number, our answer is the ICM it self i. e. 2772.

otherwise, if the ICM was not a 4 digit number, we would try to find the smallest multiple of the which would be 4 digit number.

i hope its is a help you
