The LCM of 137,726,968,643 is 255816264.
Find LCM of 137,726,968,643 with Prime Factorization
| 2 | 137, 726, 968, 643 |
| 11 | 137, 363, 484, 643 |
| 11 | 137, 33, 44, 643 |
| 137, 3, 4, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 11 x 137 x 3 x 4 x 643 = 255816264
Therefore, the lowest common multiple of 137,726,968,643 is 255816264.
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.
137 x 726 x 968 x 643 = 61907535888
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.
137 : 1, 137
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,726,968,643, is 1.
Now, the common factors can be found like this.
137:137
726:2x 3x 11x 11
968:2x 2x 2x 11x 11
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 61907535888/(1x242)
LCM = 61907535888/242
LCM = 255816264
Thus, we can understand that the LCM of 137,726,968,643 is 255816264.
