The LCM of 765,810,515,824 is 5673240.
Find LCM of 765,810,515,824 with Prime Factorization
| 2 | 765, 810, 515, 824 |
| 3 | 765, 405, 515, 412 |
| 3 | 255, 135, 515, 412 |
| 5 | 85, 45, 515, 412 |
| 103 | 17, 9, 103, 412 |
| 17, 9, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 103 x 17 x 9 x 1 x 4 = 5673240
Therefore, the lowest common multiple of 765,810,515,824 is 5673240.
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 810 x 515 x 824 = 262954674000
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
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
515 : 1, 5, 103, 515
824 : 1, 2, 4, 8, 103, 206, 412, 824
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,810,515,824, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
810:2x 3x 3x 3x 3x 5
515:5x 103
824:2x 2x 2x 103
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 5x 5x 103 = 46350
Therefore, the value for common factors is 46350.
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 = 262954674000/(1x46350)
LCM = 262954674000/46350
LCM = 5673240
Thus, we can understand that the LCM of 765,810,515,824 is 5673240.
