The LCM of 917,385,940,143,393 is 369789420.
Find LCM of 917,385,940,143,393 with Prime Factorization
| 5 | 917, 385, 940, 143, 393 |
| 7 | 917, 77, 188, 143, 393 |
| 11 | 131, 11, 188, 143, 393 |
| 131 | 131, 1, 188, 13, 393 |
| 1, 1, 188, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 131 x 1 x 1 x 188 x 13 x 3 = 369789420
Therefore, the lowest common multiple of 917,385,940,143,393 is 369789420.
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.
917 x 385 x 940 x 143 x 393 = 18650329397700
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.
917 : 1, 7, 131, 917
385 : 1, 5, 7, 11, 35, 55, 77, 385
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
143 : 1, 11, 13, 143
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,385,940,143,393, is 1.
Now, the common factors can be found like this.
917:7x 131
385:5x 7x 11
940:2x 2x 5x 47
143:11x 13
393:3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 11x 131 = 50435
Therefore, the value for common factors is 50435.
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 = 18650329397700/(1x50435)
LCM = 18650329397700/50435
LCM = 369789420
Thus, we can understand that the LCM of 917,385,940,143,393 is 369789420.
