Given numbers are 978,376,645,859
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,376,645,859 is 33956922840.
Find LCM of 978,376,645,859 with Prime Factorization
| 2 | 978, 376, 645, 859 |
| 3 | 489, 188, 645, 859 |
| 163, 188, 215, 859 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 188 x 215 x 859 = 33956922840
Therefore, the lowest common multiple of 978,376,645,859 is 33956922840.
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.
978 x 376 x 645 x 859 = 203741537040
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
376 : 1, 2, 4, 8, 47, 94, 188, 376
645 : 1, 3, 5, 15, 43, 129, 215, 645
859 : 1, 859
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,376,645,859, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
376:2x 2x 2x 47
645:3x 5x 43
859:859
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 203741537040/(1x6)
LCM = 203741537040/6
LCM = 33956922840
Thus, we can understand that the LCM of 978,376,645,859 is 33956922840.
