Given numbers are 809,275,530,781,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 809,275,530,781,870 is 145668175950.
Find LCM of 809,275,530,781,870 with Prime Factorization
| 2 | 809, 275, 530, 781, 870 |
| 5 | 809, 275, 265, 781, 435 |
| 11 | 809, 55, 53, 781, 87 |
| 809, 5, 53, 71, 87 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 809 x 5 x 53 x 71 x 87 = 145668175950
Therefore, the lowest common multiple of 809,275,530,781,870 is 145668175950.
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.
809 x 275 x 530 x 781 x 870 = 80117496772500
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.
809 : 1, 809
275 : 1, 5, 11, 25, 55, 275
530 : 1, 2, 5, 10, 53, 106, 265, 530
781 : 1, 11, 71, 781
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,275,530,781,870, is 1.
Now, the common factors can be found like this.
809:809
275:5x 5x 11
530:2x 5x 53
781:11x 71
870:2x 3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 11 = 550
Therefore, the value for common factors is 550.
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 = 80117496772500/(1x550)
LCM = 80117496772500/550
LCM = 145668175950
Thus, we can understand that the LCM of 809,275,530,781,870 is 145668175950.
