Given numbers are 820,317,362,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,317,362,634 is 47049140.
Find LCM of 820,317,362,634 with Prime Factorization
| 2 | 820, 317, 362, 634 |
| 317 | 410, 317, 181, 317 |
| 410, 1, 181, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 317 x 410 x 1 x 181 x 1 = 47049140
Therefore, the lowest common multiple of 820,317,362,634 is 47049140.
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.
820 x 317 x 362 x 634 = 59658309520
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
317 : 1, 317
362 : 1, 2, 181, 362
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,317,362,634, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
317:317
362:2x 181
634:2x 317
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 317 = 1268
Therefore, the value for common factors is 1268.
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 = 59658309520/(1x1268)
LCM = 59658309520/1268
LCM = 47049140
Thus, we can understand that the LCM of 820,317,362,634 is 47049140.
