Given numbers are 870,827,645,559
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 870,827,645,559 is 402194910.
Find LCM of 870,827,645,559 with Prime Factorization
| 3 | 870, 827, 645, 559 |
| 5 | 290, 827, 215, 559 |
| 43 | 58, 827, 43, 559 |
| 58, 827, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 43 x 58 x 827 x 1 x 13 = 402194910
Therefore, the lowest common multiple of 870,827,645,559 is 402194910.
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.
870 x 827 x 645 x 559 = 259415716950
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.
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
827 : 1, 827
645 : 1, 3, 5, 15, 43, 129, 215, 645
559 : 1, 13, 43, 559
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,827,645,559, is 1.
Now, the common factors can be found like this.
870:2x 3x 5x 29
827:827
645:3x 5x 43
559:13x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 43 = 645
Therefore, the value for common factors is 645.
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 = 259415716950/(1x645)
LCM = 259415716950/645
LCM = 402194910
Thus, we can understand that the LCM of 870,827,645,559 is 402194910.
