Find LCM of 256,775,866,780,381 with Prime Factorization
| 2 | 256, 775, 866, 780, 381 |
| 2 | 128, 775, 433, 390, 381 |
| 3 | 64, 775, 433, 195, 381 |
| 5 | 64, 775, 433, 65, 127 |
| 64, 155, 433, 13, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 64 x 155 x 433 x 13 x 127 = 425498361600
Therefore, the lowest common multiple of 256,775,866,780,381 is 425498361600.
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.
256 x 775 x 866 x 780 x 381 = 51059803392000
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
775 : 1, 5, 25, 31, 155, 775
866 : 1, 2, 433, 866
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
381 : 1, 3, 127, 381
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,775,866,780,381, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
775:5x 5x 31
866:2x 433
780:2x 2x 3x 5x 13
381:3x 127
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 5 = 120
Therefore, the value for common factors is 120.
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 = 51059803392000/(1x120)
LCM = 51059803392000/120
LCM = 425498361600
Thus, we can understand that the LCM of 256,775,866,780,381 is 425498361600.
