Given numbers are 918,311,889,836,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 918,311,889,836,490 is 3713206972860.
Find LCM of 918,311,889,836,490 with Prime Factorization
| 2 | 918, 311, 889, 836, 490 |
| 7 | 459, 311, 889, 418, 245 |
| 459, 311, 127, 418, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 459 x 311 x 127 x 418 x 35 = 3713206972860
Therefore, the lowest common multiple of 918,311,889,836,490 is 3713206972860.
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.
918 x 311 x 889 x 836 x 490 = 103969795240080
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
311 : 1, 311
889 : 1, 7, 127, 889
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,311,889,836,490, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
311:311
889:7x 127
836:2x 2x 11x 19
490:2x 5x 7x 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 7 = 28
Therefore, the value for common factors is 28.
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 = 103969795240080/(1x28)
LCM = 103969795240080/28
LCM = 3713206972860
Thus, we can understand that the LCM of 918,311,889,836,490 is 3713206972860.
