Given numbers are 814,840,830,448
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,840,830,448 is 227008320.
Find LCM of 814,840,830,448 with Prime Factorization
| 2 | 814, 840, 830, 448 |
| 2 | 407, 420, 415, 224 |
| 2 | 407, 210, 415, 112 |
| 5 | 407, 105, 415, 56 |
| 7 | 407, 21, 83, 56 |
| 407, 3, 83, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 407 x 3 x 83 x 8 = 227008320
Therefore, the lowest common multiple of 814,840,830,448 is 227008320.
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 840 x 830 x 448 = 254249318400
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
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
830 : 1, 2, 5, 10, 83, 166, 415, 830
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,840,830,448, is 2.
Now, the common factors can be found like this.
814:2x 11x 37
840:2x 2x 2x 3x 5x 7
830:2x 5x 83
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 2x 5x 7 = 560
Therefore, the value for common factors is 560.
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 = 254249318400/(2x560)
LCM = 254249318400/1120
LCM = 227008320
Thus, we can understand that the LCM of 814,840,830,448 is 227008320.
