Given numbers are 978,715,804,914,204
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,715,804,914,204 is 727972236420.
Find LCM of 978,715,804,914,204 with Prime Factorization
| 2 | 978, 715, 804, 914, 204 |
| 2 | 489, 715, 402, 457, 102 |
| 3 | 489, 715, 201, 457, 51 |
| 163, 715, 67, 457, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 163 x 715 x 67 x 457 x 17 = 727972236420
Therefore, the lowest common multiple of 978,715,804,914,204 is 727972236420.
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.
978 x 715 x 804 x 914 x 204 = 104828002044480
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
715 : 1, 5, 11, 13, 55, 65, 143, 715
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
914 : 1, 2, 457, 914
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,715,804,914,204, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
715:5x 11x 13
804:2x 2x 3x 67
914:2x 457
204:2x 2x 3x 17
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 104828002044480/(1x144)
LCM = 104828002044480/144
LCM = 727972236420
Thus, we can understand that the LCM of 978,715,804,914,204 is 727972236420.
