Question

by using division method find the lcm of 13,91,104​

Answer 1

Answer:

1456

Step-by-step explanation:

LCM means the Lowest Common Multiple.

What is lowest common multiple?

It means the lowest number of multiplication between two numbers.

For example :

Multiples of 2 :

2 , 4 , 6 , 8 , 10 , 12 , 14 , 16 , 18 , 20

Multiples of 7

7 , 14 , 21 , 28 , 35 , 42 , 49 , 56 , 63 , 70

The lowest multiple between this number is bold and underlined.

14 is the lowest common factor of 2 and 7.

This is just one of the method of doing the lowest common factor.

Imagine it is a bigger number, 5 and 120?

There is no way you can slowly view the multiples of 5 and 120, its wasting time.

To find the Lowest Common Multiple, Division Method is one of it.

And it is done using this way :

13$\sqrt{13, 91, 104}$

7$\sqrt{1, 7, 8}$

2$\sqrt{1, 1, 8}$

2$\sqrt{1, 1, 4}$

2$\sqrt{1, 1, 2}$

2$\sqrt{1, 1, 1}$

To get the LCM of 13, 91 and 104, we multiply the different factors gotten from the division method.

Factors : 13 × 7 × 2 × 2 × 2 × 2

Simply multiply the factors and there goes your lowest common multiple.

13 × 7 × 2 × 2 × 2 × 2 = 1456

1456 is your lowest common multiple
