Question

find the LCM of the following common division method 112,140,168​

Answer 1

Answer:-

L. C. M = 1,680

Given :-

112, 140 , 168

To find :-

The L. C. M with common division method.

Solution:-

$\begin{array}{r | l}</p><p>2 & 112,140,168</p><p>\cline{2-2} 2 & 56,70,84</p><p>\cline{2-2} 2 & 28 , 35 ,42 </p><p>\cline{2-2} 7 & 14 , 35 , 21</p><p>\cline{2-2} & 2, 5 ,3</p><p>\end{array}$

Now,

There is no divisible number.

Therefore,

→L. C. M = 2 × 2 × 2 × 7 × 2 × 5 × 3

→L. C. M = 1680

hence,

The L. C. M of given number by common divisor method will be 1680.
