Question

lcm and hcf of 2,3,,4 activity

Answer 1

 2 has no factors besides 1 and 2.

2 is a prime number

Since 3 has no factors besides 1 and 3

3 is a prime number

4 has factors of 2 and 2

The LCM of 2,3,4,is 2⋅2⋅3=12.

Answer 2

Given: The given numbers are 2, 3, 4.

To find: LCM and HCF of 2, 3, 4.

Solution:

To find the LCM and HCF first we will find the prime factorization of each number.

$2=2$

$3=3$

$4=2\times 2$

The LCM(2,3,4)=2×2×3=12

Therefore the LCM of 2, 3, 4 is 12.

HCF is the highest common factor.

Here, the HCF of 2,3 and 4 is 1.

Hence, the LCM is 12 and HCF is 1.
