Given numbers are 538,902,112,385,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,902,112,385,861 is 203815920.
Find LCM of 538,902,112,385,861 with Prime Factorization
| 2 | 538, 902, 112, 385, 861 |
| 7 | 269, 451, 56, 385, 861 |
| 11 | 269, 451, 8, 55, 123 |
| 41 | 269, 41, 8, 5, 123 |
| 269, 1, 8, 5, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 41 x 269 x 1 x 8 x 5 x 3 = 203815920
Therefore, the lowest common multiple of 538,902,112,385,861 is 203815920.
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.
538 x 902 x 112 x 385 x 861 = 18016512064320
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.
538 : 1, 2, 269, 538
902 : 1, 2, 11, 22, 41, 82, 451, 902
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
385 : 1, 5, 7, 11, 35, 55, 77, 385
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,902,112,385,861, is 1.
Now, the common factors can be found like this.
538:2x 269
902:2x 11x 41
112:2x 2x 2x 2x 7
385:5x 7x 11
861:3x 7x 41
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 7x 7x 11x 41 = 88396
Therefore, the value for common factors is 88396.
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 = 18016512064320/(1x88396)
LCM = 18016512064320/88396
LCM = 203815920
Thus, we can understand that the LCM of 538,902,112,385,861 is 203815920.
