Question

1. Find the L.C.M pf the following numbers using prime factorization.
24.28.196​

Answer 1

Answer:

Prime factorization of the given numbers are  

24=2×2×2×3  

28=2×2×7  

196=2×2×7×7  

Notice that 2 occurs as a prime number factor maximum 3 times , 3 one times , 7 two times  

∴ L.C.M =2×2×2×3×7×7=1176

Step-by-step explanation:

Answer 2

1176

Step-by-step explanation:

Prime factorization of the following numbers are

24 = 2*2*2*3

28 = 2*2*7

196 = 2*2*7*7

Multiply all the highest possibilities of factors to get the L.C.M

Thus, L.C.M = 2*2*2*3*7*7 = 1176
