The LCM of 779,944,442,912 is 487554288.
Find LCM of 779,944,442,912 with Prime Factorization
| 2 | 779, 944, 442, 912 |
| 2 | 779, 472, 221, 456 |
| 2 | 779, 236, 221, 228 |
| 2 | 779, 118, 221, 114 |
| 19 | 779, 59, 221, 57 |
| 41, 59, 221, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 19 x 41 x 59 x 221 x 3 = 487554288
Therefore, the lowest common multiple of 779,944,442,912 is 487554288.
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.
779 x 944 x 442 x 912 = 296433007104
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.
779 : 1, 19, 41, 779
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
442 : 1, 2, 13, 17, 26, 34, 221, 442
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,944,442,912, is 1.
Now, the common factors can be found like this.
779:19x 41
944:2x 2x 2x 2x 59
442:2x 13x 17
912:2x 2x 2x 2x 3x 19
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 19 = 608
Therefore, the value for common factors is 608.
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 = 296433007104/(1x608)
LCM = 296433007104/608
LCM = 487554288
Thus, we can understand that the LCM of 779,944,442,912 is 487554288.
