Given numbers are 807,781,840,711,999
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 807,781,840,711,999 is 4642521511320.
Find LCM of 807,781,840,711,999 with Prime Factorization
| 3 | 807, 781, 840, 711, 999 |
| 3 | 269, 781, 280, 237, 333 |
| 269, 781, 280, 79, 111 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 269 x 781 x 280 x 79 x 111 = 4642521511320
Therefore, the lowest common multiple of 807,781,840,711,999 is 4642521511320.
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.
807 x 781 x 840 x 711 x 999 = 376044242416920
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.
807 : 1, 3, 269, 807
781 : 1, 11, 71, 781
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
711 : 1, 3, 9, 79, 237, 711
999 : 1, 3, 9, 27, 37, 111, 333, 999
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,781,840,711,999, is 1.
Now, the common factors can be found like this.
807:3x 269
781:11x 71
840:2x 2x 2x 3x 5x 7
711:3x 3x 79
999:3x 3x 3x 37
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 3x 3 = 81
Therefore, the value for common factors is 81.
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 = 376044242416920/(1x81)
LCM = 376044242416920/81
LCM = 4642521511320
Thus, we can understand that the LCM of 807,781,840,711,999 is 4642521511320.
