Given numbers are 765,205,806,260
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 765,205,806,260 is 50560380.
Find LCM of 765,205,806,260 with Prime Factorization
| 2 | 765, 205, 806, 260 |
| 5 | 765, 205, 403, 130 |
| 13 | 153, 41, 403, 26 |
| 153, 41, 31, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 153 x 41 x 31 x 2 = 50560380
Therefore, the lowest common multiple of 765,205,806,260 is 50560380.
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.
765 x 205 x 806 x 260 = 32864247000
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
205 : 1, 5, 41, 205
806 : 1, 2, 13, 26, 31, 62, 403, 806
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,205,806,260, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
205:5x 41
806:2x 13x 31
260:2x 2x 5x 13
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 13 = 650
Therefore, the value for common factors is 650.
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 = 32864247000/(1x650)
LCM = 32864247000/650
LCM = 50560380
Thus, we can understand that the LCM of 765,205,806,260 is 50560380.
