Given numbers are 765,943,800,297,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 765,943,800,297,685 is 521828287200.
Find LCM of 765,943,800,297,685 with Prime Factorization
| 3 | 765, 943, 800, 297, 685 |
| 3 | 255, 943, 800, 99, 685 |
| 5 | 85, 943, 800, 33, 685 |
| 17, 943, 160, 33, 137 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 17 x 943 x 160 x 33 x 137 = 521828287200
Therefore, the lowest common multiple of 765,943,800,297,685 is 521828287200.
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 943 x 800 x 297 x 685 = 117411364620000
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
943 : 1, 23, 41, 943
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
297 : 1, 3, 9, 11, 27, 33, 99, 297
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,943,800,297,685, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
943:23x 41
800:2x 2x 2x 2x 2x 5x 5
297:3x 3x 3x 11
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5 = 225
Therefore, the value for common factors is 225.
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 = 117411364620000/(1x225)
LCM = 117411364620000/225
LCM = 521828287200
Thus, we can understand that the LCM of 765,943,800,297,685 is 521828287200.
