The LCM of 798,715,429,976 is 278438160.
Find LCM of 798,715,429,976 with Prime Factorization
| 2 | 798, 715, 429, 976 |
| 3 | 399, 715, 429, 488 |
| 11 | 133, 715, 143, 488 |
| 13 | 133, 65, 13, 488 |
| 133, 5, 1, 488 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 133 x 5 x 1 x 488 = 278438160
Therefore, the lowest common multiple of 798,715,429,976 is 278438160.
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.
798 x 715 x 429 x 976 = 238899941280
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.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
715 : 1, 5, 11, 13, 55, 65, 143, 715
429 : 1, 3, 11, 13, 33, 39, 143, 429
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,715,429,976, is 1.
Now, the common factors can be found like this.
798:2x 3x 7x 19
715:5x 11x 13
429:3x 11x 13
976:2x 2x 2x 2x 61
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 11x 13 = 858
Therefore, the value for common factors is 858.
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 = 238899941280/(1x858)
LCM = 238899941280/858
LCM = 278438160
Thus, we can understand that the LCM of 798,715,429,976 is 278438160.
