Find LCM of 779,726,462,138,454 with Prime Factorization
| 2 | 779, 726, 462, 138, 454 |
| 3 | 779, 363, 231, 69, 227 |
| 11 | 779, 121, 77, 23, 227 |
| 779, 11, 7, 23, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 779 x 11 x 7 x 23 x 227 = 20669302038
Therefore, the lowest common multiple of 779,726,462,138,454 is 20669302038.
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 726 x 462 x 138 x 454 = 16370087214096
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
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
138 : 1, 2, 3, 6, 23, 46, 69, 138
454 : 1, 2, 227, 454
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,726,462,138,454, is 1.
Now, the common factors can be found like this.
779:19x 41
726:2x 3x 11x 11
462:2x 3x 7x 11
138:2x 3x 23
454:2x 227
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 3x 3x 11 = 792
Therefore, the value for common factors is 792.
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 = 16370087214096/(1x792)
LCM = 16370087214096/792
LCM = 20669302038
Thus, we can understand that the LCM of 779,726,462,138,454 is 20669302038.
