Given numbers are 395,985,780,694,208
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 395,985,780,694,208 is 16849126320.
Find LCM of 395,985,780,694,208 with Prime Factorization
| 2 | 395, 985, 780, 694, 208 |
| 2 | 395, 985, 390, 347, 104 |
| 5 | 395, 985, 195, 347, 52 |
| 13 | 79, 197, 39, 347, 52 |
| 79, 197, 3, 347, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 79 x 197 x 3 x 347 x 4 = 16849126320
Therefore, the lowest common multiple of 395,985,780,694,208 is 16849126320.
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.
395 x 985 x 780 x 694 x 208 = 43807728432000
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.
395 : 1, 5, 79, 395
985 : 1, 5, 197, 985
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
694 : 1, 2, 347, 694
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,985,780,694,208, is 1.
Now, the common factors can be found like this.
395:5x 79
985:5x 197
780:2x 2x 3x 5x 13
694:2x 347
208:2x 2x 2x 2x 13
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 2x 5x 5x 13 = 2600
Therefore, the value for common factors is 2600.
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 = 43807728432000/(1x2600)
LCM = 43807728432000/2600
LCM = 16849126320
Thus, we can understand that the LCM of 395,985,780,694,208 is 16849126320.
