Given numbers are 215,930,538,937,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 215,930,538,937,989 is 231830787810.
Find LCM of 215,930,538,937,989 with Prime Factorization
| 2 | 215, 930, 538, 937, 989 |
| 5 | 215, 465, 269, 937, 989 |
| 43 | 43, 93, 269, 937, 989 |
| 1, 93, 269, 937, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 43 x 1 x 93 x 269 x 937 x 23 = 231830787810
Therefore, the lowest common multiple of 215,930,538,937,989 is 231830787810.
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.
215 x 930 x 538 x 937 x 989 = 99687238758300
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.
215 : 1, 5, 43, 215
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
538 : 1, 2, 269, 538
937 : 1, 937
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,930,538,937,989, is 1.
Now, the common factors can be found like this.
215:5x 43
930:2x 3x 5x 31
538:2x 269
937:937
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 43 = 430
Therefore, the value for common factors is 430.
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 = 99687238758300/(1x430)
LCM = 99687238758300/430
LCM = 231830787810
Thus, we can understand that the LCM of 215,930,538,937,989 is 231830787810.
