Given numbers are 138,920,316,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,920,316,956 is 52111560.
Find LCM of 138,920,316,956 with Prime Factorization
| 2 | 138, 920, 316, 956 |
| 2 | 69, 460, 158, 478 |
| 23 | 69, 230, 79, 239 |
| 3, 10, 79, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 3 x 10 x 79 x 239 = 52111560
Therefore, the lowest common multiple of 138,920,316,956 is 52111560.
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 920 x 316 x 956 = 38354108160
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
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
316 : 1, 2, 4, 79, 158, 316
956 : 1, 2, 4, 239, 478, 956
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,920,316,956, is 2.
Now, the common factors can be found like this.
138:2x 3x 23
920:2x 2x 2x 5x 23
316:2x 2x 79
956:2x 2x 239
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 2x 23 = 368
Therefore, the value for common factors is 368.
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 = 38354108160/(2x368)
LCM = 38354108160/736
LCM = 52111560
Thus, we can understand that the LCM of 138,920,316,956 is 52111560.
