Given numbers are 218,715,494,702
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,715,494,702 is 79961310.
Find LCM of 218,715,494,702 with Prime Factorization
| 2 | 218, 715, 494, 702 |
| 13 | 109, 715, 247, 351 |
| 109, 55, 19, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 109 x 55 x 19 x 27 = 79961310
Therefore, the lowest common multiple of 218,715,494,702 is 79961310.
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.
218 x 715 x 494 x 702 = 54053845560
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.
218 : 1, 2, 109, 218
715 : 1, 5, 11, 13, 55, 65, 143, 715
494 : 1, 2, 13, 19, 26, 38, 247, 494
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,715,494,702, is 1.
Now, the common factors can be found like this.
218:2x 109
715:5x 11x 13
494:2x 13x 19
702:2x 3x 3x 3x 13
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 13x 13 = 676
Therefore, the value for common factors is 676.
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 = 54053845560/(1x676)
LCM = 54053845560/676
LCM = 79961310
Thus, we can understand that the LCM of 218,715,494,702 is 79961310.
