Find LCM of 381,704,764,880,531 with Prime Factorization
| 2 | 381, 704, 764, 880, 531 |
| 2 | 381, 352, 382, 440, 531 |
| 2 | 381, 176, 191, 220, 531 |
| 2 | 381, 88, 191, 110, 531 |
| 3 | 381, 44, 191, 55, 531 |
| 11 | 127, 44, 191, 55, 177 |
| 127, 4, 191, 5, 177 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 11 x 127 x 4 x 191 x 5 x 177 = 45339243840
Therefore, the lowest common multiple of 381,704,764,880,531 is 45339243840.
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.
381 x 704 x 764 x 880 x 531 = 95756482990080
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.
381 : 1, 3, 127, 381
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
764 : 1, 2, 4, 191, 382, 764
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,704,764,880,531, is 1.
Now, the common factors can be found like this.
381:3x 127
704:2x 2x 2x 2x 2x 2x 11
764:2x 2x 191
880:2x 2x 2x 2x 5x 11
531:3x 3x 59
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 11 = 2112
Therefore, the value for common factors is 2112.
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 = 95756482990080/(1x2112)
LCM = 95756482990080/2112
LCM = 45339243840
Thus, we can understand that the LCM of 381,704,764,880,531 is 45339243840.
