Given numbers are 310,649,194,431,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 310,649,194,431,868 is 117756104620.
Find LCM of 310,649,194,431,868 with Prime Factorization
| 2 | 310, 649, 194, 431, 868 |
| 31 | 155, 649, 97, 431, 434 |
| 5, 649, 97, 431, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 5 x 649 x 97 x 431 x 14 = 117756104620
Therefore, the lowest common multiple of 310,649,194,431,868 is 117756104620.
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 649 x 194 x 431 x 868 = 14601756972880
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
649 : 1, 11, 59, 649
194 : 1, 2, 97, 194
431 : 1, 431
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,649,194,431,868, is 1.
Now, the common factors can be found like this.
310:2x 5x 31
649:11x 59
194:2x 97
431:431
868:2x 2x 7x 31
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 31 = 124
Therefore, the value for common factors is 124.
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 = 14601756972880/(1x124)
LCM = 14601756972880/124
LCM = 117756104620
Thus, we can understand that the LCM of 310,649,194,431,868 is 117756104620.
