Given numbers are 791,645,879,141,517
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,645,879,141,517 is 77284848795.
Find LCM of 791,645,879,141,517 with Prime Factorization
| 3 | 791, 645, 879, 141, 517 |
| 47 | 791, 215, 293, 47, 517 |
| 791, 215, 293, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 47 x 791 x 215 x 293 x 1 x 11 = 77284848795
Therefore, the lowest common multiple of 791,645,879,141,517 is 77284848795.
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.
791 x 645 x 879 x 141 x 517 = 32691491040285
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.
791 : 1, 7, 113, 791
645 : 1, 3, 5, 15, 43, 129, 215, 645
879 : 1, 3, 293, 879
141 : 1, 3, 47, 141
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,645,879,141,517, is 1.
Now, the common factors can be found like this.
791:7x 113
645:3x 5x 43
879:3x 293
141:3x 47
517:11x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 47 = 423
Therefore, the value for common factors is 423.
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 = 32691491040285/(1x423)
LCM = 32691491040285/423
LCM = 77284848795
Thus, we can understand that the LCM of 791,645,879,141,517 is 77284848795.
