Find LCM of 976,780,309,976,493 with Prime Factorization
| 2 | 976, 780, 309, 976, 493 |
| 2 | 488, 390, 309, 488, 493 |
| 2 | 244, 195, 309, 244, 493 |
| 2 | 122, 195, 309, 122, 493 |
| 3 | 61, 195, 309, 61, 493 |
| 61 | 61, 65, 103, 61, 493 |
| 1, 65, 103, 1, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 61 x 1 x 65 x 103 x 1 x 493 = 9664259280
Therefore, the lowest common multiple of 976,780,309,976,493 is 9664259280.
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.
976 x 780 x 309 x 976 x 493 = 113187804687360
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.
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
309 : 1, 3, 103, 309
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 976,780,309,976,493, is 1.
Now, the common factors can be found like this.
976:2x 2x 2x 2x 61
780:2x 2x 3x 5x 13
309:3x 103
976:2x 2x 2x 2x 61
493:17x 29
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 2x 2x 3x 61 = 11712
Therefore, the value for common factors is 11712.
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 = 113187804687360/(1x11712)
LCM = 113187804687360/11712
LCM = 9664259280
Thus, we can understand that the LCM of 976,780,309,976,493 is 9664259280.
