The LCM of 138,857,377,276,980 is 21847278180.
Find LCM of 138,857,377,276,980 with Prime Factorization
| 2 | 138, 857, 377, 276, 980 |
| 2 | 69, 857, 377, 138, 490 |
| 3 | 69, 857, 377, 69, 245 |
| 23 | 23, 857, 377, 23, 245 |
| 1, 857, 377, 1, 245 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 1 x 857 x 377 x 1 x 245 = 21847278180
Therefore, the lowest common multiple of 138,857,377,276,980 is 21847278180.
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.
138 x 857 x 377 x 276 x 980 = 12059697555360
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.
138 : 1, 2, 3, 6, 23, 46, 69, 138
857 : 1, 857
377 : 1, 13, 29, 377
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,857,377,276,980, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
857:857
377:13x 29
276:2x 2x 3x 23
980:2x 2x 5x 7x 7
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 2x 3x 23 = 552
Therefore, the value for common factors is 552.
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 = 12059697555360/(1x552)
LCM = 12059697555360/552
LCM = 21847278180
Thus, we can understand that the LCM of 138,857,377,276,980 is 21847278180.
