Find LCM of 816,305,691,391,760 with Prime Factorization
2 | 816, 305, 691, 391, 760 |
2 | 408, 305, 691, 391, 380 |
2 | 204, 305, 691, 391, 190 |
5 | 102, 305, 691, 391, 95 |
17 | 102, 61, 691, 391, 19 |
6, 61, 691, 23, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 6 x 61 x 691 x 23 x 19 = 75153546960
Therefore, the lowest common multiple of 816,305,691,391,760 is 75153546960.
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.
816 x 305 x 691 x 391 x 760 = 51104411932800
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
305 : 1, 5, 61, 305
691 : 1, 691
391 : 1, 17, 23, 391
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,305,691,391,760, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
305:5x 61
691:691
391:17x 23
760:2x 2x 2x 5x 19
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 2x 5x 17 = 680
Therefore, the value for common factors is 680.
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 = 51104411932800/(1x680)
LCM = 51104411932800/680
LCM = 75153546960
Thus, we can understand that the LCM of 816,305,691,391,760 is 75153546960.
