Given numbers are 548,638,352,396
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 548,638,352,396 is 12586464.
Find LCM of 548,638,352,396 with Prime Factorization
| 2 | 548, 638, 352, 396 |
| 2 | 274, 319, 176, 198 |
| 11 | 137, 319, 88, 99 |
| 137, 29, 8, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 137 x 29 x 8 x 9 = 12586464
Therefore, the lowest common multiple of 548,638,352,396 is 12586464.
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.
548 x 638 x 352 x 396 = 48734788608
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.
548 : 1, 2, 4, 137, 274, 548
638 : 1, 2, 11, 22, 29, 58, 319, 638
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 548,638,352,396, is 2.
Now, the common factors can be found like this.
548:2x 2x 137
638:2x 11x 29
352:2x 2x 2x 2x 2x 11
396:2x 2x 3x 3x 11
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 11x 11 = 1936
Therefore, the value for common factors is 1936.
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 = 48734788608/(2x1936)
LCM = 48734788608/3872
LCM = 12586464
Thus, we can understand that the LCM of 548,638,352,396 is 12586464.
