Given numbers are 647,310,954,346
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,310,954,346 is 16551236970.
Find LCM of 647,310,954,346 with Prime Factorization
| 2 | 647, 310, 954, 346 |
| 647, 155, 477, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 647 x 155 x 477 x 173 = 16551236970
Therefore, the lowest common multiple of 647,310,954,346 is 16551236970.
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.
647 x 310 x 954 x 346 = 66204947880
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.
647 : 1, 647
310 : 1, 2, 5, 10, 31, 62, 155, 310
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
346 : 1, 2, 173, 346
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,310,954,346, is 1.
Now, the common factors can be found like this.
647:647
310:2x 5x 31
954:2x 3x 3x 53
346:2x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 66204947880/(1x4)
LCM = 66204947880/4
LCM = 16551236970
Thus, we can understand that the LCM of 647,310,954,346 is 16551236970.
