Given numbers are 568,643,981,870,375
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 568,643,981,870,375 is 1298782197000.
Find LCM of 568,643,981,870,375 with Prime Factorization
| 2 | 568, 643, 981, 870, 375 |
| 3 | 284, 643, 981, 435, 375 |
| 5 | 284, 643, 327, 145, 125 |
| 284, 643, 327, 29, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 284 x 643 x 327 x 29 x 25 = 1298782197000
Therefore, the lowest common multiple of 568,643,981,870,375 is 1298782197000.
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.
568 x 643 x 981 x 870 x 375 = 116890397730000
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.
568 : 1, 2, 4, 8, 71, 142, 284, 568
643 : 1, 643
981 : 1, 3, 9, 109, 327, 981
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
375 : 1, 3, 5, 15, 25, 75, 125, 375
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 568,643,981,870,375, is 1.
Now, the common factors can be found like this.
568:2x 2x 2x 71
643:643
981:3x 3x 109
870:2x 3x 5x 29
375:3x 5x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 116890397730000/(1x90)
LCM = 116890397730000/90
LCM = 1298782197000
Thus, we can understand that the LCM of 568,643,981,870,375 is 1298782197000.
