The correct option is A 6
Explanation: Here, we have to find HCF of 270, 384 and 588.
STEP 1: First find the HCF of any two of the given numbers. Here, find HCF of (384, 588) first.
STEP 2: The HCF of the first two numbers which is 12 becomes the divisor and the third number 270 becomes the dividend.
STEP 3: Repeat this division process till the remainder becomes zero. The last divisor is the HCF.Here, 6 is the last divisor.
Hence, HCF of 270, 384 and 588 is 6. Therefore, we needs 6 containers so that each of them contains (270÷6=45)45 butter cookies, (384÷6=64)64 milk chocolates and (588÷6=98) plain cookies.
