The LCM of 863,484,968,689 is 575579576.
Find LCM of 863,484,968,689 with Prime Factorization
| 2 | 863, 484, 968, 689 |
| 2 | 863, 242, 484, 689 |
| 11 | 863, 121, 242, 689 |
| 11 | 863, 11, 22, 689 |
| 863, 1, 2, 689 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 11 x 863 x 1 x 2 x 689 = 575579576
Therefore, the lowest common multiple of 863,484,968,689 is 575579576.
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.
863 x 484 x 968 x 689 = 278580514784
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.
863 : 1, 863
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,484,968,689, is 1.
Now, the common factors can be found like this.
863:863
484:2x 2x 11x 11
968:2x 2x 2x 11x 11
689:13x 53
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 278580514784/(1x484)
LCM = 278580514784/484
LCM = 575579576
Thus, we can understand that the LCM of 863,484,968,689 is 575579576.
