Given numbers are 814,154,671,471
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,154,671,471 is 163709238.
Find LCM of 814,154,671,471 with Prime Factorization
| 2 | 814, 154, 671, 471 |
| 11 | 407, 77, 671, 471 |
| 37, 7, 61, 471 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 37 x 7 x 61 x 471 = 163709238
Therefore, the lowest common multiple of 814,154,671,471 is 163709238.
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.
814 x 154 x 671 x 471 = 39617635596
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
154 : 1, 2, 7, 11, 14, 22, 77, 154
671 : 1, 11, 61, 671
471 : 1, 3, 157, 471
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,154,671,471, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
154:2x 7x 11
671:11x 61
471:3x 157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 39617635596/(1x242)
LCM = 39617635596/242
LCM = 163709238
Thus, we can understand that the LCM of 814,154,671,471 is 163709238.
