Given numbers are 219,840,187,707,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 219,840,187,707,645 is 49800486120.
Find LCM of 219,840,187,707,645 with Prime Factorization
| 3 | 219, 840, 187, 707, 645 |
| 5 | 73, 280, 187, 707, 215 |
| 7 | 73, 56, 187, 707, 43 |
| 73, 8, 187, 101, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 73 x 8 x 187 x 101 x 43 = 49800486120
Therefore, the lowest common multiple of 219,840,187,707,645 is 49800486120.
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.
219 x 840 x 187 x 707 x 645 = 15687153127800
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.
219 : 1, 3, 73, 219
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
187 : 1, 11, 17, 187
707 : 1, 7, 101, 707
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 219,840,187,707,645, is 1.
Now, the common factors can be found like this.
219:3x 73
840:2x 2x 2x 3x 5x 7
187:11x 17
707:7x 101
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 15687153127800/(1x315)
LCM = 15687153127800/315
LCM = 49800486120
Thus, we can understand that the LCM of 219,840,187,707,645 is 49800486120.
