Find LCM of 438,352,825,705 with Prime Factorization
| 2 | 438, 352, 825, 705 |
| 3 | 219, 176, 825, 705 |
| 5 | 73, 176, 275, 235 |
| 11 | 73, 176, 55, 47 |
| 73, 16, 5, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 73 x 16 x 5 x 47 = 90578400
Therefore, the lowest common multiple of 438,352,825,705 is 90578400.
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 352 x 825 x 705 = 89672616000
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
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,352,825,705, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
352:2x 2x 2x 2x 2x 11
825:3x 5x 5x 11
705:3x 5x 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 3x 3x 5x 11 = 990
Therefore, the value for common factors is 990.
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 = 89672616000/(1x990)
LCM = 89672616000/990
LCM = 90578400
Thus, we can understand that the LCM of 438,352,825,705 is 90578400.
