Find LCM of 187,391,811,558,918 with Prime Factorization
| 2 | 187, 391, 811, 558, 918 |
| 3 | 187, 391, 811, 279, 459 |
| 3 | 187, 391, 811, 93, 153 |
| 17 | 187, 391, 811, 31, 51 |
| 11, 23, 811, 31, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 11 x 23 x 811 x 31 x 3 = 5839097814
Therefore, the lowest common multiple of 187,391,811,558,918 is 5839097814.
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.
187 x 391 x 811 x 558 x 918 = 30374986828428
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.
187 : 1, 11, 17, 187
391 : 1, 17, 23, 391
811 : 1, 811
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,391,811,558,918, is 1.
Now, the common factors can be found like this.
187:11x 17
391:17x 23
811:811
558:2x 3x 3x 31
918:2x 3x 3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 17x 17 = 5202
Therefore, the value for common factors is 5202.
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 = 30374986828428/(1x5202)
LCM = 30374986828428/5202
LCM = 5839097814
Thus, we can understand that the LCM of 187,391,811,558,918 is 5839097814.
