Given numbers are 388,524,388,216,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 388,524,388,216,780 is 178406280.
Find LCM of 388,524,388,216,780 with Prime Factorization
| 2 | 388, 524, 388, 216, 780 |
| 2 | 194, 262, 194, 108, 390 |
| 3 | 97, 131, 97, 54, 195 |
| 97 | 97, 131, 97, 18, 65 |
| 1, 131, 1, 18, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 97 x 1 x 131 x 1 x 18 x 65 = 178406280
Therefore, the lowest common multiple of 388,524,388,216,780 is 178406280.
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.
388 x 524 x 388 x 216 x 780 = 13290554234880
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.
388 : 1, 2, 4, 97, 194, 388
524 : 1, 2, 4, 131, 262, 524
388 : 1, 2, 4, 97, 194, 388
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
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
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,524,388,216,780, is 4.
Now, the common factors can be found like this.
388:2x 2x 97
524:2x 2x 131
388:2x 2x 97
216:2x 2x 2x 3x 3x 3
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 2x 2x 2x 3x 97 = 18624
Therefore, the value for common factors is 18624.
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 = 13290554234880/(4x18624)
LCM = 13290554234880/74496
LCM = 178406280
Thus, we can understand that the LCM of 388,524,388,216,780 is 178406280.
