Given numbers are 978,870,566,341,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,870,566,341,812 is 191591266020.
Find LCM of 978,870,566,341,812 with Prime Factorization
| 2 | 978, 870, 566, 341, 812 |
| 3 | 489, 435, 283, 341, 406 |
| 29 | 163, 145, 283, 341, 406 |
| 163, 5, 283, 341, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 163 x 5 x 283 x 341 x 14 = 191591266020
Therefore, the lowest common multiple of 978,870,566,341,812 is 191591266020.
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 870 x 566 x 341 x 812 = 133347521149920
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
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
566 : 1, 2, 283, 566
341 : 1, 11, 31, 341
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,870,566,341,812, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
870:2x 3x 5x 29
566:2x 283
341:11x 31
812:2x 2x 7x 29
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 3x 29 = 696
Therefore, the value for common factors is 696.
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 = 133347521149920/(1x696)
LCM = 133347521149920/696
LCM = 191591266020
Thus, we can understand that the LCM of 978,870,566,341,812 is 191591266020.
