Given numbers are 580,870,940
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 580,870,940 is 81780.
Find LCM of 580,870,940 with Prime Factorization
| 2 | 580, 870, 940 |
| 2 | 290, 435, 470 |
| 5 | 145, 435, 235 |
| 29 | 29, 87, 47 |
| 1, 3, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 29 x 1 x 3 x 47 = 81780
Therefore, the lowest common multiple of 580,870,940 is 81780.
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.
580 x 870 x 940 = 474324000
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.
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
10 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 580,870,940, is 10.
Now, the common factors can be found like this.
580:2x 2x 5x 29
870:2x 3x 5x 29
940:2x 2x 5x 47
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 5x 29 = 580
Therefore, the value for common factors is 580.
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 = 474324000/(10x580)
LCM = 474324000/5800
LCM = 81780
Thus, we can understand that the LCM of 580,870,940 is 81780.
