Given numbers are 966,381,825,859,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 966,381,825,859,638 is 840436108050.
Find LCM of 966,381,825,859,638 with Prime Factorization
| 2 | 966, 381, 825, 859, 638 |
| 3 | 483, 381, 825, 859, 319 |
| 11 | 161, 127, 275, 859, 319 |
| 161, 127, 25, 859, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 161 x 127 x 25 x 859 x 29 = 840436108050
Therefore, the lowest common multiple of 966,381,825,859,638 is 840436108050.
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.
966 x 381 x 825 x 859 x 638 = 166406349393900
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.
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
381 : 1, 3, 127, 381
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
859 : 1, 859
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 966,381,825,859,638, is 1.
Now, the common factors can be found like this.
966:2x 3x 7x 23
381:3x 127
825:3x 5x 5x 11
859:859
638:2x 11x 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 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 166406349393900/(1x198)
LCM = 166406349393900/198
LCM = 840436108050
Thus, we can understand that the LCM of 966,381,825,859,638 is 840436108050.
