The LCM of 801,416,260,979 is 18326880.
Find LCM of 801,416,260,979 with Prime Factorization
| 2 | 801, 416, 260, 979 |
| 2 | 801, 208, 130, 979 |
| 13 | 801, 104, 65, 979 |
| 89 | 801, 8, 5, 979 |
| 9, 8, 5, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 89 x 9 x 8 x 5 x 11 = 18326880
Therefore, the lowest common multiple of 801,416,260,979 is 18326880.
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.
801 x 416 x 260 x 979 = 84816800640
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.
801 : 1, 3, 9, 89, 267, 801
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,416,260,979, is 1.
Now, the common factors can be found like this.
801:3x 3x 89
416:2x 2x 2x 2x 2x 13
260:2x 2x 5x 13
979:11x 89
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 13x 89 = 4628
Therefore, the value for common factors is 4628.
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 = 84816800640/(1x4628)
LCM = 84816800640/4628
LCM = 18326880
Thus, we can understand that the LCM of 801,416,260,979 is 18326880.
