Find LCM of 517,215,598,977,780 with Prime Factorization
| 2 | 517, 215, 598, 977, 780 |
| 5 | 517, 215, 299, 977, 390 |
| 13 | 517, 43, 299, 977, 78 |
| 517, 43, 23, 977, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 517 x 43 x 23 x 977 x 6 = 389651184780
Therefore, the lowest common multiple of 517,215,598,977,780 is 389651184780.
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 215 x 598 x 977 x 780 = 50654654021400
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
215 : 1, 5, 43, 215
598 : 1, 2, 13, 23, 26, 46, 299, 598
977 : 1, 977
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,215,598,977,780, is 1.
Now, the common factors can be found like this.
517:11x 47
215:5x 43
598:2x 13x 23
977:977
780:2x 2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 50654654021400/(1x130)
LCM = 50654654021400/130
LCM = 389651184780
Thus, we can understand that the LCM of 517,215,598,977,780 is 389651184780.
