Given numbers are 705,628,982,813,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,628,982,813,765 is 3004482784140.
Find LCM of 705,628,982,813,765 with Prime Factorization
| 2 | 705, 628, 982, 813, 765 |
| 3 | 705, 314, 491, 813, 765 |
| 5 | 235, 314, 491, 271, 255 |
| 47, 314, 491, 271, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 47 x 314 x 491 x 271 x 51 = 3004482784140
Therefore, the lowest common multiple of 705,628,982,813,765 is 3004482784140.
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.
705 x 628 x 982 x 813 x 765 = 270403450572600
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
628 : 1, 2, 4, 157, 314, 628
982 : 1, 2, 491, 982
813 : 1, 3, 271, 813
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,628,982,813,765, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
628:2x 2x 157
982:2x 491
813:3x 271
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 270403450572600/(1x90)
LCM = 270403450572600/90
LCM = 3004482784140
Thus, we can understand that the LCM of 705,628,982,813,765 is 3004482784140.
