Find LCM of 231,838,591,452,448 with Prime Factorization
| 2 | 231, 838, 591, 452, 448 |
| 2 | 231, 419, 591, 226, 224 |
| 3 | 231, 419, 591, 113, 112 |
| 7 | 77, 419, 197, 113, 112 |
| 11, 419, 197, 113, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 419 x 197 x 113 x 16 = 137895675456
Therefore, the lowest common multiple of 231,838,591,452,448 is 137895675456.
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.
231 x 838 x 591 x 452 x 448 = 23166473476608
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
838 : 1, 2, 419, 838
591 : 1, 3, 197, 591
452 : 1, 2, 4, 113, 226, 452
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,838,591,452,448, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
838:2x 419
591:3x 197
452:2x 2x 113
448:2x 2x 2x 2x 2x 2x 7
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 7 = 168
Therefore, the value for common factors is 168.
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 = 23166473476608/(1x168)
LCM = 23166473476608/168
LCM = 137895675456
Thus, we can understand that the LCM of 231,838,591,452,448 is 137895675456.
