Answer 1

Answer:

Answer 2

11844

Step-by-step explanation:

To find the LCM by prime factorisation of 84, 36, 94

First of all we have to find prime factors of 84, 36, 94

prime factors of 84 -

2 | 84

2 | 42

3 | 21

7

=> 84 = 2×2×3×7

prime factors of 36 -

2 | 36

2 | 18

3 | 9

3

=> 36 = 2×2×3×3

prime factors of 94 -

2 | 94

47

=> 94 = 2×47

Now,

only 2×2×3 is the common factor in atleast two numbers & remaining factors are (7×3×47)

So,

LCM = 2×2×3×3×7×47

=> 11844

So,

the LCM is 11844
