Given numbers are 888,870,554,831
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 888,870,554,831 is 35666520.
Find LCM of 888,870,554,831 with Prime Factorization
| 2 | 888, 870, 554, 831 |
| 3 | 444, 435, 277, 831 |
| 277 | 148, 145, 277, 277 |
| 148, 145, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 277 x 148 x 145 x 1 x 1 = 35666520
Therefore, the lowest common multiple of 888,870,554,831 is 35666520.
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.
888 x 870 x 554 x 831 = 355666537440
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.
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
554 : 1, 2, 277, 554
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 888,870,554,831, is 1.
Now, the common factors can be found like this.
888:2x 2x 2x 3x 37
870:2x 3x 5x 29
554:2x 277
831:3x 277
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 277 = 9972
Therefore, the value for common factors is 9972.
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 = 355666537440/(1x9972)
LCM = 355666537440/9972
LCM = 35666520
Thus, we can understand that the LCM of 888,870,554,831 is 35666520.
