Find LCM of 353,784,388,931,813 with Prime Factorization
| 2 | 353, 784, 388, 931, 813 |
| 2 | 353, 392, 194, 931, 813 |
| 7 | 353, 196, 97, 931, 813 |
| 7 | 353, 28, 97, 133, 813 |
| 353, 4, 97, 19, 813 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 353 x 4 x 97 x 19 x 813 = 414673849968
Therefore, the lowest common multiple of 353,784,388,931,813 is 414673849968.
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.
353 x 784 x 388 x 931 x 813 = 81276074593728
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.
353 : 1, 353
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
388 : 1, 2, 4, 97, 194, 388
931 : 1, 7, 19, 49, 133, 931
813 : 1, 3, 271, 813
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 353,784,388,931,813, is 1.
Now, the common factors can be found like this.
353:353
784:2x 2x 2x 2x 7x 7
388:2x 2x 97
931:7x 7x 19
813:3x 271
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 81276074593728/(1x196)
LCM = 81276074593728/196
LCM = 414673849968
Thus, we can understand that the LCM of 353,784,388,931,813 is 414673849968.
