Given numbers are 646,850,560,798
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,850,560,798 is 2713200.
Find LCM of 646,850,560,798 with Prime Factorization
| 2 | 646, 850, 560, 798 |
| 5 | 323, 425, 280, 399 |
| 7 | 323, 85, 56, 399 |
| 17 | 323, 85, 8, 57 |
| 19 | 19, 5, 8, 57 |
| 1, 5, 8, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 17 x 19 x 1 x 5 x 8 x 3 = 2713200
Therefore, the lowest common multiple of 646,850,560,798 is 2713200.
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.
646 x 850 x 560 x 798 = 245381808000
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,850,560,798, is 2.
Now, the common factors can be found like this.
646:2x 17x 19
850:2x 5x 5x 17
560:2x 2x 2x 2x 5x 7
798:2x 3x 7x 19
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 5x 7x 17x 19 = 45220
Therefore, the value for common factors is 45220.
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 = 245381808000/(2x45220)
LCM = 245381808000/90440
LCM = 2713200
Thus, we can understand that the LCM of 646,850,560,798 is 2713200.
