Ques 1)
The LCM of 5 and 12 is:
60
Ques 2)
GCF of 72 and 81 is: 9
Ques 3)
72 + 81 =9 (8+9)
Explanation:Ques 1)
We know that the LCM (least common multiple) of two numbers is calculated by :
Firstly finding all the factors of both the numbers.Then multiply each factor the greatest number of times it occur in either of the two numbers.Here we have two numbers as:
5 and 12
5=5×1
and 12=2×2×3×1
Hence, LCM(5,12)=2×2×3×5×1=60
Ques 2)
We know that GCF(greatest common factor) are the multiplication of the factors which are common to both the numbers.
72=1×2×2×2×3×3
81=1×3×3×3×3
Hence, we have:
GCF(72,81)=1×3×3=9
Ques 3)
72+81 could be written as:
72+81=9(8+9)
Hence, 8 and 9 don't have a common factor.
