Find LCM of 517,718,465,651,840 with Prime Factorization
| 2 | 517, 718, 465, 651, 840 |
| 3 | 517, 359, 465, 651, 420 |
| 5 | 517, 359, 155, 217, 140 |
| 7 | 517, 359, 31, 217, 28 |
| 31 | 517, 359, 31, 31, 4 |
| 517, 359, 1, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 31 x 517 x 359 x 1 x 1 x 4 = 4833102120
Therefore, the lowest common multiple of 517,718,465,651,840 is 4833102120.
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.
517 x 718 x 465 x 651 x 840 = 94390484403600
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.
517 : 1, 11, 47, 517
718 : 1, 2, 359, 718
465 : 1, 3, 5, 15, 31, 93, 155, 465
651 : 1, 3, 7, 21, 31, 93, 217, 651
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,718,465,651,840, is 1.
Now, the common factors can be found like this.
517:11x 47
718:2x 359
465:3x 5x 31
651:3x 7x 31
840:2x 2x 2x 3x 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 3x 3x 5x 7x 31 = 19530
Therefore, the value for common factors is 19530.
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 = 94390484403600/(1x19530)
LCM = 94390484403600/19530
LCM = 4833102120
Thus, we can understand that the LCM of 517,718,465,651,840 is 4833102120.
