Find LCM of 405,459,778,774,354 with Prime Factorization
| 2 | 405, 459, 778, 774, 354 |
| 3 | 405, 459, 389, 387, 177 |
| 3 | 135, 153, 389, 129, 59 |
| 3 | 45, 51, 389, 43, 59 |
| 15, 17, 389, 43, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 15 x 17 x 389 x 43 x 59 = 13589516610
Therefore, the lowest common multiple of 405,459,778,774,354 is 13589516610.
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.
405 x 459 x 778 x 774 x 354 = 39627030434760
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
459 : 1, 3, 9, 17, 27, 51, 153, 459
778 : 1, 2, 389, 778
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
354 : 1, 2, 3, 6, 59, 118, 177, 354
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,459,778,774,354, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
459:3x 3x 3x 17
778:2x 389
774:2x 3x 3x 43
354:2x 3x 59
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 3 = 2916
Therefore, the value for common factors is 2916.
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 = 39627030434760/(1x2916)
LCM = 39627030434760/2916
LCM = 13589516610
Thus, we can understand that the LCM of 405,459,778,774,354 is 13589516610.
