Given numbers are 551,815,725,163
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,815,725,163 is 2245325.
Find LCM of 551,815,725,163 with Prime Factorization
| 5 | 551, 815, 725, 163 |
| 29 | 551, 163, 145, 163 |
| 163 | 19, 163, 5, 163 |
| 19, 1, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 29 x 163 x 19 x 1 x 5 x 1 = 2245325
Therefore, the lowest common multiple of 551,815,725,163 is 2245325.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
551 x 815 x 725 x 163 = 53068256375
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
551 : 1, 19, 29, 551
815 : 1, 5, 163, 815
725 : 1, 5, 25, 29, 145, 725
163 : 1, 163
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,815,725,163, is 1.
Now, the common factors can be found like this.
551:19x 29
815:5x 163
725:5x 5x 29
163:163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 29x 163 = 23635
Therefore, the value for common factors is 23635.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 53068256375/(1x23635)
LCM = 53068256375/23635
LCM = 2245325
Thus, we can understand that the LCM of 551,815,725,163 is 2245325.
