Given numbers are 438,675,948,468
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,675,948,468 is 202421700.
Find LCM of 438,675,948,468 with Prime Factorization
| 2 | 438, 675, 948, 468 |
| 2 | 219, 675, 474, 234 |
| 3 | 219, 675, 237, 117 |
| 3 | 73, 225, 79, 39 |
| 73, 75, 79, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 73 x 75 x 79 x 13 = 202421700
Therefore, the lowest common multiple of 438,675,948,468 is 202421700.
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.
438 x 675 x 948 x 468 = 131169261600
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,675,948,468, is 3.
Now, the common factors can be found like this.
438:2x 3x 73
675:3x 3x 3x 5x 5
948:2x 2x 3x 79
468:2x 2x 3x 3x 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 3 = 216
Therefore, the value for common factors is 216.
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 = 131169261600/(3x216)
LCM = 131169261600/648
LCM = 202421700
Thus, we can understand that the LCM of 438,675,948,468 is 202421700.
