Given numbers are 915,849,300,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 915,849,300,168 is 72504600.
Find LCM of 915,849,300,168 with Prime Factorization
| 2 | 915, 849, 300, 168 |
| 2 | 915, 849, 150, 84 |
| 3 | 915, 849, 75, 42 |
| 5 | 305, 283, 25, 14 |
| 61, 283, 5, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 61 x 283 x 5 x 14 = 72504600
Therefore, the lowest common multiple of 915,849,300,168 is 72504600.
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.
915 x 849 x 300 x 168 = 39152484000
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.
915 : 1, 3, 5, 15, 61, 183, 305, 915
849 : 1, 3, 283, 849
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,849,300,168, is 3.
Now, the common factors can be found like this.
915:3x 5x 61
849:3x 283
300:2x 2x 3x 5x 5
168:2x 2x 2x 3x 7
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 5 = 180
Therefore, the value for common factors is 180.
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 = 39152484000/(3x180)
LCM = 39152484000/540
LCM = 72504600
Thus, we can understand that the LCM of 915,849,300,168 is 72504600.
