Find LCM of 399,820,788,836,525 with Prime Factorization
| 2 | 399, 820, 788, 836, 525 |
| 2 | 399, 410, 394, 418, 525 |
| 3 | 399, 205, 197, 209, 525 |
| 5 | 133, 205, 197, 209, 175 |
| 7 | 133, 41, 197, 209, 35 |
| 19 | 19, 41, 197, 209, 5 |
| 1, 41, 197, 11, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 19 x 1 x 41 x 197 x 11 x 5 = 3544995300
Therefore, the lowest common multiple of 399,820,788,836,525 is 3544995300.
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.
399 x 820 x 788 x 836 x 525 = 113156249976000
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
788 : 1, 2, 4, 197, 394, 788
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,820,788,836,525, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
820:2x 2x 5x 41
788:2x 2x 197
836:2x 2x 11x 19
525:3x 5x 5x 7
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 3x 5x 7x 19 = 31920
Therefore, the value for common factors is 31920.
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 = 113156249976000/(1x31920)
LCM = 113156249976000/31920
LCM = 3544995300
Thus, we can understand that the LCM of 399,820,788,836,525 is 3544995300.
