Given numbers are 715,916,806,930
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,916,806,930 is 60909420.
Find LCM of 715,916,806,930 with Prime Factorization
| 2 | 715, 916, 806, 930 |
| 5 | 715, 458, 403, 465 |
| 13 | 143, 458, 403, 93 |
| 31 | 11, 458, 31, 93 |
| 11, 458, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 31 x 11 x 458 x 1 x 3 = 60909420
Therefore, the lowest common multiple of 715,916,806,930 is 60909420.
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.
715 x 916 x 806 x 930 = 490929925200
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
916 : 1, 2, 4, 229, 458, 916
806 : 1, 2, 13, 26, 31, 62, 403, 806
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,916,806,930, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
916:2x 2x 229
806:2x 13x 31
930:2x 3x 5x 31
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 5x 13x 31 = 8060
Therefore, the value for common factors is 8060.
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 = 490929925200/(1x8060)
LCM = 490929925200/8060
LCM = 60909420
Thus, we can understand that the LCM of 715,916,806,930 is 60909420.
