what is the lcm of 1 and 208?
lcm (1 208) = (?)
1 => 1
208 => 2 x 2 x 2 x 2 x 13
= 1 x 2 x 2 x 2 x 2 x 13
= 208
lcm (1 and 208) = 208
208 is the LCM of 1 and 208.
where,
1 is a positive integer,
208 is a positive integer,
208 is the LCM of 1 and 208,
There is no common factors of 1 and 208 in {1, 2 x 2 x 2 x 2 x 13},
{1 x 2 x 2 x 2 x 2 x 13} in {1, 2 x 2 x 2 x 2 x 13} are the uncommon factors of 1 and 208.
Use in Mathematics: LCM of 1 and 208
The below are some of the mathematical applications where lcm of 1 and 208 can be used:
- to find the least number which is exactly divisible by 1 and 208.
- to find the common denominator for two fractions having 1 and 208 as denominators in the unlike fractions addition or subtraction.
In the context of lcm real world problems, the lcm of 1 and 208 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 1 seconds and bell B tolls at 208 seconds repeatedly. The answer is that all bells A and B toll together at 208 seconds for the first time, at 416 seconds for the second time, at 624 seconds for the third time and so on.
Important Notes: 1 and 208 lcm
The below are the important notes to be remembered while solving the lcm of 1 and 208:
- The common prime factors and the remaining prime factors of 1 and 208 should be multiplied to find the least common multiple of 1 and 208, when solving lcm by using prime factors method.
- The results of lcm of 1 and 208, and the lcm of 208 and 1 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 1 and 208?

Solved example using prime factors method:
What is the LCM of 1 and 208?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 1
B = 208
What to be found:
find the lcm of 1 and 208
step 2 Find the prime factors of 1 and 208:
Prime factors of 1 = 1
Prime factors of 208 = 2 x 2 x 2 x 2 x 13
step 3Identify the repeated and non-repeated prime factors of 1 and 208:
Since there is no common factors between 1 and 208, multiplying the given numbers directly provides the LCM of
1 and 208.
= 1 x 208
= 208
lcm(1 and 208) = 208
Hence,
lcm of 1 and 208 is 208
This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 1 and 208.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 1 and 208
What to be found:
lcm (1, 208) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
1 and 208
step 3 Choose the divisor which divides each or most of the given integers (1 and 208), 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 1 and 208 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 1 | 208 |
| 2 | 1 | 104 |
| 2 | 1 | 52 |
| 2 | 1 | 26 |
| 13 | 1 | 13 |
| 1 | 1 |
step 4 Multiply the divisors to find the lcm of 1 and 208:
= 2 x 2 x 2 x 2 x 13
= 208
LCM(1, 208) = 208
The LCM of two numbers 1 and 208 is 208
