Given numbers are 891,468,541,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,468,541,557 is 13961545884.
Find LCM of 891,468,541,557 with Prime Factorization
| 3 | 891, 468, 541, 557 |
| 3 | 297, 156, 541, 557 |
| 99, 52, 541, 557 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 99 x 52 x 541 x 557 = 13961545884
Therefore, the lowest common multiple of 891,468,541,557 is 13961545884.
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.
891 x 468 x 541 x 557 = 125653912956
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
541 : 1, 541
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,468,541,557, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
468:2x 2x 3x 3x 13
541:541
557:557
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 125653912956/(1x9)
LCM = 125653912956/9
LCM = 13961545884
Thus, we can understand that the LCM of 891,468,541,557 is 13961545884.
