Given numbers are 545,636,484,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,636,484,891 is 1132407540.
Find LCM of 545,636,484,891 with Prime Factorization
| 2 | 545, 636, 484, 891 |
| 2 | 545, 318, 242, 891 |
| 3 | 545, 159, 121, 891 |
| 11 | 545, 53, 121, 297 |
| 545, 53, 11, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 545 x 53 x 11 x 27 = 1132407540
Therefore, the lowest common multiple of 545,636,484,891 is 1132407540.
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.
545 x 636 x 484 x 891 = 149477795280
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.
545 : 1, 5, 109, 545
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,636,484,891, is 1.
Now, the common factors can be found like this.
545:5x 109
636:2x 2x 3x 53
484:2x 2x 11x 11
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 149477795280/(1x132)
LCM = 149477795280/132
LCM = 1132407540
Thus, we can understand that the LCM of 545,636,484,891 is 1132407540.
