Given numbers are 920,654,261,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,654,261,870 is 26173080.
Find LCM of 920,654,261,870 with Prime Factorization
| 2 | 920, 654, 261, 870 |
| 3 | 460, 327, 261, 435 |
| 5 | 460, 109, 87, 145 |
| 29 | 92, 109, 87, 29 |
| 92, 109, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 29 x 92 x 109 x 3 x 1 = 26173080
Therefore, the lowest common multiple of 920,654,261,870 is 26173080.
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.
920 x 654 x 261 x 870 = 136623477600
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
654 : 1, 2, 3, 6, 109, 218, 327, 654
261 : 1, 3, 9, 29, 87, 261
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,654,261,870, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
654:2x 3x 109
261:3x 3x 29
870:2x 3x 5x 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 3x 3x 5x 29 = 5220
Therefore, the value for common factors is 5220.
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 = 136623477600/(1x5220)
LCM = 136623477600/5220
LCM = 26173080
Thus, we can understand that the LCM of 920,654,261,870 is 26173080.
