Given numbers are 138,893,817,311
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,893,817,311 is 1648008282.
Find LCM of 138,893,817,311 with Prime Factorization
| 19 | 138, 893, 817, 311 |
| 138, 47, 43, 311 |
Multiply the prime numbers at the bottom and the left side.
19 x 138 x 47 x 43 x 311 = 1648008282
Therefore, the lowest common multiple of 138,893,817,311 is 1648008282.
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 893 x 817 x 311 = 31312157358
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
893 : 1, 19, 47, 893
817 : 1, 19, 43, 817
311 : 1, 311
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,893,817,311, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
893:19x 47
817:19x 43
311:311
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 31312157358/(1x19)
LCM = 31312157358/19
LCM = 1648008282
Thus, we can understand that the LCM of 138,893,817,311 is 1648008282.
