Given numbers are 814,696,680,841
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,696,680,841 is 698265480.
Find LCM of 814,696,680,841 with Prime Factorization
| 2 | 814, 696, 680, 841 |
| 2 | 407, 348, 340, 841 |
| 2 | 407, 174, 170, 841 |
| 29 | 407, 87, 85, 841 |
| 407, 3, 85, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 29 x 407 x 3 x 85 x 29 = 698265480
Therefore, the lowest common multiple of 814,696,680,841 is 698265480.
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 696 x 680 x 841 = 323995182720
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
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,696,680,841, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
696:2x 2x 2x 3x 29
680:2x 2x 2x 5x 17
841:29x 29
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 29 = 464
Therefore, the value for common factors is 464.
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 = 323995182720/(1x464)
LCM = 323995182720/464
LCM = 698265480
Thus, we can understand that the LCM of 814,696,680,841 is 698265480.
