Given numbers are 931,487,721,516,843
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,487,721,516,843 is 6771297395436.
Find LCM of 931,487,721,516,843 with Prime Factorization
| 3 | 931, 487, 721, 516, 843 |
| 7 | 931, 487, 721, 172, 281 |
| 133, 487, 103, 172, 281 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 133 x 487 x 103 x 172 x 281 = 6771297395436
Therefore, the lowest common multiple of 931,487,721,516,843 is 6771297395436.
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.
931 x 487 x 721 x 516 x 843 = 142197245304156
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.
931 : 1, 7, 19, 49, 133, 931
487 : 1, 487
721 : 1, 7, 103, 721
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
843 : 1, 3, 281, 843
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,487,721,516,843, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
487:487
721:7x 103
516:2x 2x 3x 43
843:3x 281
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 142197245304156/(1x21)
LCM = 142197245304156/21
LCM = 6771297395436
Thus, we can understand that the LCM of 931,487,721,516,843 is 6771297395436.
