Find LCM of 391,935,258,930,786 with Prime Factorization
| 2 | 391, 935, 258, 930, 786 |
| 3 | 391, 935, 129, 465, 393 |
| 5 | 391, 935, 43, 155, 131 |
| 17 | 391, 187, 43, 31, 131 |
| 23, 11, 43, 31, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 23 x 11 x 43 x 31 x 131 = 22531605690
Therefore, the lowest common multiple of 391,935,258,930,786 is 22531605690.
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.
391 x 935 x 258 x 930 x 786 = 68946713411400
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.
391 : 1, 17, 23, 391
935 : 1, 5, 11, 17, 55, 85, 187, 935
258 : 1, 2, 3, 6, 43, 86, 129, 258
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,935,258,930,786, is 1.
Now, the common factors can be found like this.
391:17x 23
935:5x 11x 17
258:2x 3x 43
930:2x 3x 5x 31
786:2x 3x 131
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 3x 3x 5x 17 = 3060
Therefore, the value for common factors is 3060.
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 = 68946713411400/(1x3060)
LCM = 68946713411400/3060
LCM = 22531605690
Thus, we can understand that the LCM of 391,935,258,930,786 is 22531605690.
