Given numbers are 579,838,936,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 579,838,936,780 is 378457560.
Find LCM of 579,838,936,780 with Prime Factorization
| 2 | 579, 838, 936, 780 |
| 2 | 579, 419, 468, 390 |
| 3 | 579, 419, 234, 195 |
| 13 | 193, 419, 78, 65 |
| 193, 419, 6, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 193 x 419 x 6 x 5 = 378457560
Therefore, the lowest common multiple of 579,838,936,780 is 378457560.
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.
579 x 838 x 936 x 780 = 354236276160
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.
579 : 1, 3, 193, 579
838 : 1, 2, 419, 838
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
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 579,838,936,780, is 1.
Now, the common factors can be found like this.
579:3x 193
838:2x 419
936:2x 2x 2x 3x 3x 13
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 2x 2x 3x 3x 13 = 936
Therefore, the value for common factors is 936.
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 = 354236276160/(1x936)
LCM = 354236276160/936
LCM = 378457560
Thus, we can understand that the LCM of 579,838,936,780 is 378457560.
