Given numbers are 156,687,185,915,890
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 156,687,185,915,890 is 35879935260.
Find LCM of 156,687,185,915,890 with Prime Factorization
| 2 | 156, 687, 185, 915, 890 |
| 3 | 78, 687, 185, 915, 445 |
| 5 | 26, 229, 185, 305, 445 |
| 26, 229, 37, 61, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 26 x 229 x 37 x 61 x 89 = 35879935260
Therefore, the lowest common multiple of 156,687,185,915,890 is 35879935260.
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.
156 x 687 x 185 x 915 x 890 = 16145970867000
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
687 : 1, 3, 229, 687
185 : 1, 5, 37, 185
915 : 1, 3, 5, 15, 61, 183, 305, 915
890 : 1, 2, 5, 10, 89, 178, 445, 890
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,687,185,915,890, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
687:3x 229
185:5x 37
915:3x 5x 61
890:2x 5x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 16145970867000/(1x450)
LCM = 16145970867000/450
LCM = 35879935260
Thus, we can understand that the LCM of 156,687,185,915,890 is 35879935260.
