Question

Find the LCM of the given number by prime factorization method 48, 80, 1 12​

Answer 1

Answer:

Step-by-step explanation:

It is given that we need to find the LCM of the following numbers in prime factorisation method.

So, we can do this :-

2 [ 48,80,112]

2 [24,40,56]

2[12,20,28]

2 [06,10,14]

2 [03,05,07]

LCM = 2 * 2 * 2 * 2 * 2 * 3 * 5 * 7

= 32 * 25 * 7

= 224 * 25

= 5600 is the required answer to the above question.

LCM means Least Common Multiple, and the method to to is given above. Insert lines (horizontal and vertical) instead of brackets$.$

Answer 2

Answer:

Step-by-step explanation:

Least Common Multiple is :  1680

Calculate Least Common Multiple for :  48, 80 and 112

Factorize of the above numbers :

   48 = 24 • 3  

   80 = 24 • 5  

   112 = 24 • 7

Build a prime factors table

Number of times each prime factor

appears in the factorization of :

Prime  Factor      Number  48   Number  80   Number  112    L.C.M    (max)  

   2          4                       4                 4                      4

  3            1                       0                 0                      1

  5          0                      1                  0                      1

  7          0                      0                  1                       1

hope this help you
