Given numbers are 988,382,763,420,866
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 988,382,763,420,866 is 935177404980.
Find LCM of 988,382,763,420,866 with Prime Factorization
| 2 | 988, 382, 763, 420, 866 |
| 2 | 494, 191, 763, 210, 433 |
| 7 | 247, 191, 763, 105, 433 |
| 247, 191, 109, 15, 433 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 247 x 191 x 109 x 15 x 433 = 935177404980
Therefore, the lowest common multiple of 988,382,763,420,866 is 935177404980.
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.
988 x 382 x 763 x 420 x 866 = 104739869357760
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
382 : 1, 2, 191, 382
763 : 1, 7, 109, 763
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
866 : 1, 2, 433, 866
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,382,763,420,866, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
382:2x 191
763:7x 109
420:2x 2x 3x 5x 7
866:2x 433
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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 104739869357760/(1x112)
LCM = 104739869357760/112
LCM = 935177404980
Thus, we can understand that the LCM of 988,382,763,420,866 is 935177404980.
