Given numbers are 158,812,138,684
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 158,812,138,684 is 252294084.
Find LCM of 158,812,138,684 with Prime Factorization
| 2 | 158, 812, 138, 684 |
| 2 | 79, 406, 69, 342 |
| 3 | 79, 203, 69, 171 |
| 79, 203, 23, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 79 x 203 x 23 x 57 = 252294084
Therefore, the lowest common multiple of 158,812,138,684 is 252294084.
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.
158 x 812 x 138 x 684 = 12110116032
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.
158 : 1, 2, 79, 158
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
138 : 1, 2, 3, 6, 23, 46, 69, 138
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,812,138,684, is 2.
Now, the common factors can be found like this.
158:2x 79
812:2x 2x 7x 29
138:2x 3x 23
684:2x 2x 3x 3x 19
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 3 = 24
Therefore, the value for common factors is 24.
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 = 12110116032/(2x24)
LCM = 12110116032/48
LCM = 252294084
Thus, we can understand that the LCM of 158,812,138,684 is 252294084.
