Given numbers are 310,922,638,855,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 310,922,638,855,646 is 132525159030.
Find LCM of 310,922,638,855,646 with Prime Factorization
| 2 | 310, 922, 638, 855, 646 |
| 5 | 155, 461, 319, 855, 323 |
| 19 | 31, 461, 319, 171, 323 |
| 31, 461, 319, 9, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 31 x 461 x 319 x 9 x 17 = 132525159030
Therefore, the lowest common multiple of 310,922,638,855,646 is 132525159030.
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.
310 x 922 x 638 x 855 x 646 = 100719120862800
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.
310 : 1, 2, 5, 10, 31, 62, 155, 310
922 : 1, 2, 461, 922
638 : 1, 2, 11, 22, 29, 58, 319, 638
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,922,638,855,646, is 1.
Now, the common factors can be found like this.
310:2x 5x 31
922:2x 461
638:2x 11x 29
855:3x 3x 5x 19
646:2x 17x 19
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 5x 19 = 760
Therefore, the value for common factors is 760.
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 = 100719120862800/(1x760)
LCM = 100719120862800/760
LCM = 132525159030
Thus, we can understand that the LCM of 310,922,638,855,646 is 132525159030.
