Given numbers are 780,923,289,556,376
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,923,289,556,376 is 209118978120.
Find LCM of 780,923,289,556,376 with Prime Factorization
| 2 | 780, 923, 289, 556, 376 |
| 2 | 390, 923, 289, 278, 188 |
| 13 | 195, 923, 289, 139, 94 |
| 15, 71, 289, 139, 94 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 15 x 71 x 289 x 139 x 94 = 209118978120
Therefore, the lowest common multiple of 780,923,289,556,376 is 209118978120.
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.
780 x 923 x 289 x 556 x 376 = 43496747448960
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.
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
923 : 1, 13, 71, 923
289 : 1, 17, 289
556 : 1, 2, 4, 139, 278, 556
376 : 1, 2, 4, 8, 47, 94, 188, 376
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,923,289,556,376, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
923:13x 71
289:17x 17
556:2x 2x 139
376:2x 2x 2x 47
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 2x 13 = 208
Therefore, the value for common factors is 208.
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 = 43496747448960/(1x208)
LCM = 43496747448960/208
LCM = 209118978120
Thus, we can understand that the LCM of 780,923,289,556,376 is 209118978120.
