Given numbers are 851,961,396,930
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,961,396,930 is 1619265780.
Find LCM of 851,961,396,930 with Prime Factorization
| 2 | 851, 961, 396, 930 |
| 3 | 851, 961, 198, 465 |
| 31 | 851, 961, 66, 155 |
| 851, 31, 66, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 851 x 31 x 66 x 5 = 1619265780
Therefore, the lowest common multiple of 851,961,396,930 is 1619265780.
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.
851 x 961 x 396 x 930 = 301183435080
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.
851 : 1, 23, 37, 851
961 : 1, 31, 961
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
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 851,961,396,930, is 1.
Now, the common factors can be found like this.
851:23x 37
961:31x 31
396:2x 2x 3x 3x 11
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 3x 31 = 186
Therefore, the value for common factors is 186.
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 = 301183435080/(1x186)
LCM = 301183435080/186
LCM = 1619265780
Thus, we can understand that the LCM of 851,961,396,930 is 1619265780.
