Given numbers are 166,795,678,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 166,795,678,840 is 417553080.
Find LCM of 166,795,678,840 with Prime Factorization
| 2 | 166, 795, 678, 840 |
| 3 | 83, 795, 339, 420 |
| 5 | 83, 265, 113, 140 |
| 83, 53, 113, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 83 x 53 x 113 x 28 = 417553080
Therefore, the lowest common multiple of 166,795,678,840 is 417553080.
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.
166 x 795 x 678 x 840 = 75159554400
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.
166 : 1, 2, 83, 166
795 : 1, 3, 5, 15, 53, 159, 265, 795
678 : 1, 2, 3, 6, 113, 226, 339, 678
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 166,795,678,840, is 1.
Now, the common factors can be found like this.
166:2x 83
795:3x 5x 53
678:2x 3x 113
840:2x 2x 2x 3x 5x 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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 75159554400/(1x180)
LCM = 75159554400/180
LCM = 417553080
Thus, we can understand that the LCM of 166,795,678,840 is 417553080.
