Find LCM of 810,861,671,187,550 with Prime Factorization
| 2 | 810, 861, 671, 187, 550 |
| 3 | 405, 861, 671, 187, 275 |
| 5 | 135, 287, 671, 187, 275 |
| 11 | 27, 287, 671, 187, 55 |
| 27, 287, 61, 17, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 27 x 287 x 61 x 17 x 5 = 13258926450
Therefore, the lowest common multiple of 810,861,671,187,550 is 13258926450.
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.
810 x 861 x 671 x 187 x 550 = 48129903013500
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
861 : 1, 3, 7, 21, 41, 123, 287, 861
671 : 1, 11, 61, 671
187 : 1, 11, 17, 187
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,861,671,187,550, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
861:3x 7x 41
671:11x 61
187:11x 17
550:2x 5x 5x 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 3x 5x 11x 11 = 3630
Therefore, the value for common factors is 3630.
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 = 48129903013500/(1x3630)
LCM = 48129903013500/3630
LCM = 13258926450
Thus, we can understand that the LCM of 810,861,671,187,550 is 13258926450.
