lcm (13, 16 and 26) = 208
208 is the lcm of 13, 16 and 26.
where,
13 is a positive integer,
16 is a positive integer,
208 is the lcm of 13, 16 and 26,
{2, 13} in {13, 2 x 2 x 2 x 2, 2 x 13} are the most repeated factors of 13, 16 and 26,
{2, 2, 2} in {13, 2 x 2 x 2 x 2, 2 x 13} are the the other remaining factors of 13, 16 and 26.
Use in Mathematics: LCM of 13, 16 and 26
The below are some of the mathematical applications where lcm of 13, 16 and 26 can be used:
- to find the least number which is exactly divisible by 13, 16 and 26.
- to find the common denominators for the fractions having 13, 16 and 26 as denominators in the unlike fractions addition or subtraction.
In the context of lcm real world problems, the lcm of 13, 16 and 26 helps to find the exact time when three similar and recurring 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 all the bells A, B and C toll together, if bell A tolls at 13 seconds, B tolls at 16 seconds and C tolls at 26 seconds repeatedly. The answer is that all bells A, B and C 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: 13, 16 and 26 lcm
The below are the important notes to be remembered while solving the lcm of 13, 16 and 26:
- The repeated and non-repeated prime factors of 13, 16 and 26 should be multiplied to find the least common multiple of 13, 16 and 26, when solving lcm by using prime factors method.
- The results of lcm of 13, 16 and 26 is identical even if we change the order of given numbers in the lcm calculation, it means the order of given numbers in the lcm calculation doesn't affect the results.
