Given numbers are 806,402,645,688,486
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,402,645,688,486 is 22570675920.
Find LCM of 806,402,645,688,486 with Prime Factorization
| 2 | 806, 402, 645, 688, 486 |
| 3 | 403, 201, 645, 344, 243 |
| 43 | 403, 67, 215, 344, 81 |
| 403, 67, 5, 8, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 403 x 67 x 5 x 8 x 81 = 22570675920
Therefore, the lowest common multiple of 806,402,645,688,486 is 22570675920.
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.
806 x 402 x 645 x 688 x 486 = 69878812648320
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
402 : 1, 2, 3, 6, 67, 134, 201, 402
645 : 1, 3, 5, 15, 43, 129, 215, 645
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,402,645,688,486, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
402:2x 3x 67
645:3x 5x 43
688:2x 2x 2x 2x 43
486:2x 3x 3x 3x 3x 3
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 3x 3x 43 = 3096
Therefore, the value for common factors is 3096.
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 = 69878812648320/(1x3096)
LCM = 69878812648320/3096
LCM = 22570675920
Thus, we can understand that the LCM of 806,402,645,688,486 is 22570675920.
