Answers
answer is 4 I could not send the full paper sorry
Given : 16, 88 and 324
To Find : HCF
Solution:
HCF Highest common factor of given numbers is the largest factors which divides all the given numbers perfectly.
HCF = product of common factors of least power
LCM - Least common multiplier of given numbers is the least number which is perfectly divisible by given numbers.
LCM = product of each factor of highest power
16 88 324
2 8 44 162
2 4 22 81
HCF =2 * 2 = 4
