Given numbers are 704,917,780,766
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 704,917,780,766 is 48214246080.
Find LCM of 704,917,780,766 with Prime Factorization
| 2 | 704, 917, 780, 766 |
| 2 | 352, 917, 390, 383 |
| 176, 917, 195, 383 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 176 x 917 x 195 x 383 = 48214246080
Therefore, the lowest common multiple of 704,917,780,766 is 48214246080.
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.
704 x 917 x 780 x 766 = 385713968640
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.
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
917 : 1, 7, 131, 917
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
766 : 1, 2, 383, 766
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,917,780,766, is 1.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
917:7x 131
780:2x 2x 3x 5x 13
766:2x 383
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 2 = 8
Therefore, the value for common factors is 8.
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 = 385713968640/(1x8)
LCM = 385713968640/8
LCM = 48214246080
Thus, we can understand that the LCM of 704,917,780,766 is 48214246080.
