Given numbers are 898,520,870,520
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 898,520,870,520 is 20312760.
Find LCM of 898,520,870,520 with Prime Factorization
| 2 | 898, 520, 870, 520 |
| 2 | 449, 260, 435, 260 |
| 2 | 449, 130, 435, 130 |
| 5 | 449, 65, 435, 65 |
| 13 | 449, 13, 87, 13 |
| 449, 1, 87, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 13 x 449 x 1 x 87 x 1 = 20312760
Therefore, the lowest common multiple of 898,520,870,520 is 20312760.
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.
898 x 520 x 870 x 520 = 211252704000
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.
898 : 1, 2, 449, 898
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,520,870,520, is 2.
Now, the common factors can be found like this.
898:2x 449
520:2x 2x 2x 5x 13
870:2x 3x 5x 29
520:2x 2x 2x 5x 13
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 5x 13 = 5200
Therefore, the value for common factors is 5200.
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 = 211252704000/(2x5200)
LCM = 211252704000/10400
LCM = 20312760
Thus, we can understand that the LCM of 898,520,870,520 is 20312760.
