Find LCM of 784,957,454,656,186 with Prime Factorization
| 2 | 784, 957, 454, 656, 186 |
| 2 | 392, 957, 227, 328, 93 |
| 2 | 196, 957, 227, 164, 93 |
| 2 | 98, 957, 227, 82, 93 |
| 3 | 49, 957, 227, 41, 93 |
| 49, 319, 227, 41, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 49 x 319 x 227 x 41 x 31 = 216470842896
Therefore, the lowest common multiple of 784,957,454,656,186 is 216470842896.
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.
784 x 957 x 454 x 656 x 186 = 41562401836032
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
957 : 1, 3, 11, 29, 33, 87, 319, 957
454 : 1, 2, 227, 454
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
186 : 1, 2, 3, 6, 31, 62, 93, 186
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,957,454,656,186, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
957:3x 11x 29
454:2x 227
656:2x 2x 2x 2x 41
186:2x 3x 31
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 3 = 192
Therefore, the value for common factors is 192.
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 = 41562401836032/(1x192)
LCM = 41562401836032/192
LCM = 216470842896
Thus, we can understand that the LCM of 784,957,454,656,186 is 216470842896.
