Find LCM of 788,394,639,357,799 with Prime Factorization
| 2 | 788, 394, 639, 357, 799 |
| 3 | 394, 197, 639, 357, 799 |
| 17 | 394, 197, 213, 119, 799 |
| 197 | 394, 197, 213, 7, 47 |
| 2, 1, 213, 7, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 197 x 2 x 1 x 213 x 7 x 47 = 2816254476
Therefore, the lowest common multiple of 788,394,639,357,799 is 2816254476.
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.
788 x 394 x 639 x 357 x 799 = 56589817440744
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.
788 : 1, 2, 4, 197, 394, 788
394 : 1, 2, 197, 394
639 : 1, 3, 9, 71, 213, 639
357 : 1, 3, 7, 17, 21, 51, 119, 357
799 : 1, 17, 47, 799
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,394,639,357,799, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
394:2x 197
639:3x 3x 71
357:3x 7x 17
799:17x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17x 197 = 20094
Therefore, the value for common factors is 20094.
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 = 56589817440744/(1x20094)
LCM = 56589817440744/20094
LCM = 2816254476
Thus, we can understand that the LCM of 788,394,639,357,799 is 2816254476.
