Given numbers are 982,840,286,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 982,840,286,770 is 58978920.
Find LCM of 982,840,286,770 with Prime Factorization
| 2 | 982, 840, 286, 770 |
| 5 | 491, 420, 143, 385 |
| 7 | 491, 84, 143, 77 |
| 11 | 491, 12, 143, 11 |
| 491, 12, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 491 x 12 x 13 x 1 = 58978920
Therefore, the lowest common multiple of 982,840,286,770 is 58978920.
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.
982 x 840 x 286 x 770 = 181655073600
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.
982 : 1, 2, 491, 982
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
286 : 1, 2, 11, 13, 22, 26, 143, 286
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 982,840,286,770, is 2.
Now, the common factors can be found like this.
982:2x 491
840:2x 2x 2x 3x 5x 7
286:2x 11x 13
770:2x 5x 7x 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 5x 7x 11 = 1540
Therefore, the value for common factors is 1540.
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 = 181655073600/(2x1540)
LCM = 181655073600/3080
LCM = 58978920
Thus, we can understand that the LCM of 982,840,286,770 is 58978920.
