Find LCM of 946,390,418,672,779 with Prime Factorization
| 2 | 946, 390, 418, 672, 779 |
| 3 | 473, 195, 209, 336, 779 |
| 11 | 473, 65, 209, 112, 779 |
| 19 | 43, 65, 19, 112, 779 |
| 43, 65, 1, 112, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 19 x 43 x 65 x 1 x 112 x 41 = 16094638560
Therefore, the lowest common multiple of 946,390,418,672,779 is 16094638560.
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.
946 x 390 x 418 x 672 x 779 = 80730707016960
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.
946 : 1, 2, 11, 22, 43, 86, 473, 946
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
418 : 1, 2, 11, 19, 22, 38, 209, 418
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,390,418,672,779, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
390:2x 3x 5x 13
418:2x 11x 19
672:2x 2x 2x 2x 2x 3x 7
779:19x 41
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 11x 19 = 5016
Therefore, the value for common factors is 5016.
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 = 80730707016960/(1x5016)
LCM = 80730707016960/5016
LCM = 16094638560
Thus, we can understand that the LCM of 946,390,418,672,779 is 16094638560.
