Given numbers are 219,666,484,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 219,666,484,840 is 823588920.
Find LCM of 219,666,484,840 with Prime Factorization
| 2 | 219, 666, 484, 840 |
| 2 | 219, 333, 242, 420 |
| 3 | 219, 333, 121, 210 |
| 73, 111, 121, 70 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 73 x 111 x 121 x 70 = 823588920
Therefore, the lowest common multiple of 219,666,484,840 is 823588920.
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 666 x 484 x 840 = 59298402240
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
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 219,666,484,840, is 1.
Now, the common factors can be found like this.
219:3x 73
666:2x 3x 3x 37
484:2x 2x 11x 11
840:2x 2x 2x 3x 5x 7
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 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 59298402240/(1x72)
LCM = 59298402240/72
LCM = 823588920
Thus, we can understand that the LCM of 219,666,484,840 is 823588920.
