Given numbers are 871,321,846,642,930
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 871,321,846,642,930 is 12220922610.
Find LCM of 871,321,846,642,930 with Prime Factorization
| 2 | 871, 321, 846, 642, 930 |
| 3 | 871, 321, 423, 321, 465 |
| 107 | 871, 107, 141, 107, 155 |
| 871, 1, 141, 1, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 871 x 1 x 141 x 1 x 155 = 12220922610
Therefore, the lowest common multiple of 871,321,846,642,930 is 12220922610.
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.
871 x 321 x 846 x 642 x 930 = 141224981681160
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.
871 : 1, 13, 67, 871
321 : 1, 3, 107, 321
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
642 : 1, 2, 3, 6, 107, 214, 321, 642
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,321,846,642,930, is 1.
Now, the common factors can be found like this.
871:13x 67
321:3x 107
846:2x 3x 3x 47
642:2x 3x 107
930:2x 3x 5x 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 3x 3x 3x 107 = 11556
Therefore, the value for common factors is 11556.
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 = 141224981681160/(1x11556)
LCM = 141224981681160/11556
LCM = 12220922610
Thus, we can understand that the LCM of 871,321,846,642,930 is 12220922610.
