LCM of 10 and 1
10 is the LCM of 10 and 1. The step-by-step solution using prime factors and special division methods is one of the simple methods to easily understand how to find what is the LCM of 10 and 1, provided along with the use cases of mathematics and real-world problems.
what is the lcm of 10 and 1?
lcm (10 1) = (?)
10 => 2 x 5
1 => 1
= 2 x 5 x 1
= 10
lcm (10 and 1) = 10
10 is the LCM of 10 and 1.
where,
10 is a positive integer,
1 is a positive integer,
10 is the LCM of 10 and 1,
There is no common factors of 10 and 1 in {2 x 5, 1},
{2 x 5 x 1} in {2 x 5, 1} are the uncommon factors of 10 and 1.
Use in Mathematics: LCM of 10 and 1
The below are some of the mathematical applications where lcm of 10 and 1 can be used:
- to find the least number which is exactly divisible by 10 and 1.
- to find the common denominator for two fractions having 10 and 1 as denominators in the unlike fractions addition or subtraction.
In the context of lcm real world problems, the lcm of 10 and 1 helps to find the exact time when two similar and recurring events with different time schedule happens together at the same time. For example, the real world problems involve lcm in situations to find at what time the bells A and B all toll together, if bell A tolls at 10 seconds and bell B tolls at 1 seconds repeatedly. The answer is that all bells A and B toll together at 10 seconds for the first time, at 20 seconds for the second time, at 30 seconds for the third time and so on.
Important Notes: 10 and 1 lcm
The below are the important notes to be remembered while solving the lcm of 10 and 1:
- The common prime factors and the remaining prime factors of 10 and 1 should be multiplied to find the least common multiple of 10 and 1, when solving lcm by using prime factors method.
- The results of lcm of 10 and 1, and the lcm of 1 and 10 are identical, it means the order of given numbers in the lcm calculation doesn't affect the results.
How-to: What is the LCM of 10 and 1?
The below solved example with step by step work shows how to find what is the lcm of 10 and 1 by using prime factors method and division method.
Solved example using prime factors method:
What is the LCM of 10 and 1?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 10
B = 1
What to be found:
find the lcm of 10 and 1
step 2 Find the prime factors of 10 and 1:
Prime factors of 10 = 2 x 5
Prime factors of 1 = 1
step 3Identify the repeated and non-repeated prime factors of 10 and 1:
Since there is no common factors between 10 and 1, multiplying the given numbers directly provides the LCM of
10 and 1.
= 10 x 1
= 10
lcm(10 and 1) = 10
Hence,
lcm of 10 and 1 is 10
This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 10 and 1.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 10 and 1
What to be found:
lcm (10, 1) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
10 and 1
step 3 Choose the divisor which divides each or most of the given integers (10 and 1), divide each integers separately and write down the quotient in the next line right under the respective integers. Bring down the integer to the next line if any integer in 10 and 1 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 10 | 1 |
| 5 | 5 | 1 |
| 1 | 1 |
step 4 Multiply the divisors to find the lcm of 10 and 1:
= 2 x 5
= 10
LCM(10, 1) = 10
The LCM of two numbers 10 and 1 is 10
