The LCM of 684,798,254,891 is 60199524.
Find LCM of 684,798,254,891 with Prime Factorization
| 2 | 684, 798, 254, 891 |
| 3 | 342, 399, 127, 891 |
| 3 | 114, 133, 127, 297 |
| 19 | 38, 133, 127, 99 |
| 2, 7, 127, 99 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 2 x 7 x 127 x 99 = 60199524
Therefore, the lowest common multiple of 684,798,254,891 is 60199524.
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.
684 x 798 x 254 x 891 = 123529423248
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
254 : 1, 2, 127, 254
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,798,254,891, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
798:2x 3x 7x 19
254:2x 127
891:3x 3x 3x 3x 11
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 3x 3x 3x 19 = 2052
Therefore, the value for common factors is 2052.
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 = 123529423248/(1x2052)
LCM = 123529423248/2052
LCM = 60199524
Thus, we can understand that the LCM of 684,798,254,891 is 60199524.
