The LCM of 389,767,715,854,305 is 14014110110.
Find LCM of 389,767,715,854,305 with Prime Factorization
| 5 | 389, 767, 715, 854, 305 |
| 13 | 389, 767, 143, 854, 61 |
| 61 | 389, 59, 11, 854, 61 |
| 389, 59, 11, 14, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 61 x 389 x 59 x 11 x 14 x 1 = 14014110110
Therefore, the lowest common multiple of 389,767,715,854,305 is 14014110110.
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.
389 x 767 x 715 x 854 x 305 = 55565946586150
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.
389 : 1, 389
767 : 1, 13, 59, 767
715 : 1, 5, 11, 13, 55, 65, 143, 715
854 : 1, 2, 7, 14, 61, 122, 427, 854
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,767,715,854,305, is 1.
Now, the common factors can be found like this.
389:389
767:13x 59
715:5x 11x 13
854:2x 7x 61
305:5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13x 61 = 3965
Therefore, the value for common factors is 3965.
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 = 55565946586150/(1x3965)
LCM = 55565946586150/3965
LCM = 14014110110
Thus, we can understand that the LCM of 389,767,715,854,305 is 14014110110.
