Find LCM of 759,816,646,666,345 with Prime Factorization
| 2 | 759, 816, 646, 666, 345 |
| 3 | 759, 408, 323, 333, 345 |
| 17 | 253, 136, 323, 111, 115 |
| 23 | 253, 8, 19, 111, 115 |
| 11, 8, 19, 111, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 23 x 11 x 8 x 19 x 111 x 5 = 2176994160
Therefore, the lowest common multiple of 759,816,646,666,345 is 2176994160.
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.
759 x 816 x 646 x 666 x 345 = 91930109388480
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.
759 : 1, 3, 11, 23, 33, 69, 253, 759
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
646 : 1, 2, 17, 19, 34, 38, 323, 646
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 759,816,646,666,345, is 1.
Now, the common factors can be found like this.
759:3x 11x 23
816:2x 2x 2x 2x 3x 17
646:2x 17x 19
666:2x 3x 3x 37
345:3x 5x 23
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 3x 3x 17x 23 = 42228
Therefore, the value for common factors is 42228.
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 = 91930109388480/(1x42228)
LCM = 91930109388480/42228
LCM = 2176994160
Thus, we can understand that the LCM of 759,816,646,666,345 is 2176994160.
