Common Mistakes and How to Avoid Them in LCM of 26 and 91

While solving problems on LCM, children are likely to make common mistakes, here are a few mistakes and how to avoid them.

Problem 1

Verify if the relationship LCM (26,91) x GCF(26,91) = 26 × 91 holds.

Okay, lets begin

Step 1: Calculate the LCM and GCF of 26 and 91


LCM (26,91)=182


GCF(26,91)=13


Step 2: Verify the relationship:


LCM(26,91)×GCF(26,91)=182×13=2366


182 × 13 =2366


26 × 91=2366.
 

Explanation

The relationship holds true because 2366=2366.

Problem 2

Solve the following expression using LCM of 26 and 91: 1/26 + 1/91

Okay, lets begin

 The sum of 1/26 and 1/91simplifies to  9/182using the LCM as a common denominator.
 

Explanation

Calculate the LCM of 26 and 91:


LCM(26,91)=182

1/26 = 1x7/26 x 7 , 1x2/91x2=2/182

Add the fractions:


7/182 + 2/182 = 9/182

Problem 3

If a contractor works every 26 days and a supplier delivers materials every 91 days, how many times will they meet in 1000 days?

Okay, lets begin

LCM(26,91)=182


Number of meetings = 1000/182 


 = 5 meetings.


So, they will meet 5 times.
 

Explanation

They will meet 5 times in 1000 days because the LCM of their cycles is 182 days, and 1000 divided by 182 gives approximately 5 complete overlaps.
