Given numbers are 258,530,138,781,374
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 258,530,138,781,374 is 20878215270.
Find LCM of 258,530,138,781,374 with Prime Factorization
| 2 | 258, 530, 138, 781, 374 |
| 3 | 129, 265, 69, 781, 187 |
| 11 | 43, 265, 23, 781, 187 |
| 43, 265, 23, 71, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 43 x 265 x 23 x 71 x 17 = 20878215270
Therefore, the lowest common multiple of 258,530,138,781,374 is 20878215270.
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.
258 x 530 x 138 x 781 x 374 = 5511848831280
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.
258 : 1, 2, 3, 6, 43, 86, 129, 258
530 : 1, 2, 5, 10, 53, 106, 265, 530
138 : 1, 2, 3, 6, 23, 46, 69, 138
781 : 1, 11, 71, 781
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,530,138,781,374, is 1.
Now, the common factors can be found like this.
258:2x 3x 43
530:2x 5x 53
138:2x 3x 23
781:11x 71
374:2x 11x 17
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 11 = 264
Therefore, the value for common factors is 264.
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 = 5511848831280/(1x264)
LCM = 5511848831280/264
LCM = 20878215270
Thus, we can understand that the LCM of 258,530,138,781,374 is 20878215270.
