Given numbers are 116,870,156,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 116,870,156,915 is 1379820.
Find LCM of 116,870,156,915 with Prime Factorization
| 2 | 116, 870, 156, 915 |
| 2 | 58, 435, 78, 915 |
| 3 | 29, 435, 39, 915 |
| 5 | 29, 145, 13, 305 |
| 29 | 29, 29, 13, 61 |
| 1, 1, 13, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 29 x 1 x 1 x 13 x 61 = 1379820
Therefore, the lowest common multiple of 116,870,156,915 is 1379820.
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.
116 x 870 x 156 x 915 = 14405320800
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.
116 : 1, 2, 4, 29, 58, 116
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 116,870,156,915, is 1.
Now, the common factors can be found like this.
116:2x 2x 29
870:2x 3x 5x 29
156:2x 2x 3x 13
915:3x 5x 61
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 2x 3x 3x 5x 29 = 10440
Therefore, the value for common factors is 10440.
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 = 14405320800/(1x10440)
LCM = 14405320800/10440
LCM = 1379820
Thus, we can understand that the LCM of 116,870,156,915 is 1379820.
