Find LCM of 806,621,702,441,280 with Prime Factorization
| 2 | 806, 621, 702, 441, 280 |
| 3 | 403, 621, 351, 441, 140 |
| 3 | 403, 207, 117, 147, 140 |
| 3 | 403, 69, 39, 49, 140 |
| 7 | 403, 23, 13, 49, 140 |
| 13 | 403, 23, 13, 7, 20 |
| 31, 23, 1, 7, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 13 x 31 x 23 x 1 x 7 x 20 = 490515480
Therefore, the lowest common multiple of 806,621,702,441,280 is 490515480.
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 621 x 702 x 441 x 280 = 43387075236960
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
621 : 1, 3, 9, 23, 27, 69, 207, 621
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,621,702,441,280, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
621:3x 3x 3x 23
702:2x 3x 3x 3x 13
441:3x 3x 7x 7
280:2x 2x 2x 5x 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 3x 3x 3x 3x 3x 7x 13 = 88452
Therefore, the value for common factors is 88452.
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 = 43387075236960/(1x88452)
LCM = 43387075236960/88452
LCM = 490515480
Thus, we can understand that the LCM of 806,621,702,441,280 is 490515480.
