The LCM of 647,447,894,958 is 277062222.
Find LCM of 647,447,894,958 with Prime Factorization
| 2 | 647, 447, 894, 958 |
| 3 | 647, 447, 447, 479 |
| 149 | 647, 149, 149, 479 |
| 647, 1, 1, 479 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 149 x 647 x 1 x 1 x 479 = 277062222
Therefore, the lowest common multiple of 647,447,894,958 is 277062222.
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 447 x 894 x 958 = 247693626468
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
447 : 1, 3, 149, 447
894 : 1, 2, 3, 6, 149, 298, 447, 894
958 : 1, 2, 479, 958
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,447,894,958, is 1.
Now, the common factors can be found like this.
647:647
447:3x 149
894:2x 3x 149
958:2x 479
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 149 = 894
Therefore, the value for common factors is 894.
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 = 247693626468/(1x894)
LCM = 247693626468/894
LCM = 277062222
Thus, we can understand that the LCM of 647,447,894,958 is 277062222.
