Given numbers are 790,243,516,392,617
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,243,516,392,617 is 998258589720.
Find LCM of 790,243,516,392,617 with Prime Factorization
| 2 | 790, 243, 516, 392, 617 |
| 2 | 395, 243, 258, 196, 617 |
| 3 | 395, 243, 129, 98, 617 |
| 395, 81, 43, 98, 617 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 395 x 81 x 43 x 98 x 617 = 998258589720
Therefore, the lowest common multiple of 790,243,516,392,617 is 998258589720.
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.
790 x 243 x 516 x 392 x 617 = 23958206153280
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
243 : 1, 3, 9, 27, 81, 243
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
617 : 1, 617
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,243,516,392,617, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
243:3x 3x 3x 3x 3
516:2x 2x 3x 43
392:2x 2x 2x 7x 7
617:617
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 3 = 24
Therefore, the value for common factors is 24.
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 = 23958206153280/(1x24)
LCM = 23958206153280/24
LCM = 998258589720
Thus, we can understand that the LCM of 790,243,516,392,617 is 998258589720.
