Given numbers are 334,978,685,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 334,978,685,815 is 111878310.
Find LCM of 334,978,685,815 with Prime Factorization
| 2 | 334, 978, 685, 815 |
| 5 | 167, 489, 685, 815 |
| 163 | 167, 489, 137, 163 |
| 167, 3, 137, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 163 x 167 x 3 x 137 x 1 = 111878310
Therefore, the lowest common multiple of 334,978,685,815 is 111878310.
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.
334 x 978 x 685 x 815 = 182361645300
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.
334 : 1, 2, 167, 334
978 : 1, 2, 3, 6, 163, 326, 489, 978
685 : 1, 5, 137, 685
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 334,978,685,815, is 1.
Now, the common factors can be found like this.
334:2x 167
978:2x 3x 163
685:5x 137
815:5x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 163 = 1630
Therefore, the value for common factors is 1630.
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 = 182361645300/(1x1630)
LCM = 182361645300/1630
LCM = 111878310
Thus, we can understand that the LCM of 334,978,685,815 is 111878310.
