Given numbers are 240,855,957,939,970
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 240,855,957,939,970 is 132492975120.
Find LCM of 240,855,957,939,970 with Prime Factorization
| 2 | 240, 855, 957, 939, 970 |
| 3 | 120, 855, 957, 939, 485 |
| 5 | 40, 285, 319, 313, 485 |
| 8, 57, 319, 313, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 8 x 57 x 319 x 313 x 97 = 132492975120
Therefore, the lowest common multiple of 240,855,957,939,970 is 132492975120.
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.
240 x 855 x 957 x 939 x 970 = 178865516412000
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.
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
957 : 1, 3, 11, 29, 33, 87, 319, 957
939 : 1, 3, 313, 939
970 : 1, 2, 5, 10, 97, 194, 485, 970
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,855,957,939,970, is 1.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
855:3x 3x 5x 19
957:3x 11x 29
939:3x 313
970:2x 5x 97
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 3x 3x 5x 5 = 1350
Therefore, the value for common factors is 1350.
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 = 178865516412000/(1x1350)
LCM = 178865516412000/1350
LCM = 132492975120
Thus, we can understand that the LCM of 240,855,957,939,970 is 132492975120.
