Find LCM of 760,916,979,315,819 with Prime Factorization
| 2 | 760, 916, 979, 315, 819 |
| 2 | 380, 458, 979, 315, 819 |
| 3 | 190, 229, 979, 315, 819 |
| 3 | 190, 229, 979, 105, 273 |
| 5 | 190, 229, 979, 35, 91 |
| 7 | 38, 229, 979, 7, 91 |
| 38, 229, 979, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 38 x 229 x 979 x 1 x 13 = 139545446040
Therefore, the lowest common multiple of 760,916,979,315,819 is 139545446040.
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.
760 x 916 x 979 x 315 x 819 = 175827262010400
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.
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
916 : 1, 2, 4, 229, 458, 916
979 : 1, 11, 89, 979
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,916,979,315,819, is 1.
Now, the common factors can be found like this.
760:2x 2x 2x 5x 19
916:2x 2x 229
979:11x 89
315:3x 3x 5x 7
819:3x 3x 7x 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 3x 3x 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 175827262010400/(1x1260)
LCM = 175827262010400/1260
LCM = 139545446040
Thus, we can understand that the LCM of 760,916,979,315,819 is 139545446040.
