Given numbers are 765,484,958,870,215
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 765,484,958,870,215 is 221161111380.
Find LCM of 765,484,958,870,215 with Prime Factorization
| 2 | 765, 484, 958, 870, 215 |
| 3 | 765, 242, 479, 435, 215 |
| 5 | 255, 242, 479, 145, 215 |
| 51, 242, 479, 29, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 51 x 242 x 479 x 29 x 43 = 221161111380
Therefore, the lowest common multiple of 765,484,958,870,215 is 221161111380.
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 484 x 958 x 870 x 215 = 66348333414000
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
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
958 : 1, 2, 479, 958
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,484,958,870,215, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
484:2x 2x 11x 11
958:2x 479
870:2x 3x 5x 29
215:5x 43
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 66348333414000/(1x300)
LCM = 66348333414000/300
LCM = 221161111380
Thus, we can understand that the LCM of 765,484,958,870,215 is 221161111380.
