Find LCM of 689,723,888,629,666 with Prime Factorization
| 2 | 689, 723, 888, 629, 666 |
| 3 | 689, 723, 444, 629, 333 |
| 37 | 689, 241, 148, 629, 111 |
| 689, 241, 4, 17, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 37 x 689 x 241 x 4 x 17 x 3 = 7520027112
Therefore, the lowest common multiple of 689,723,888,629,666 is 7520027112.
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.
689 x 723 x 888 x 629 x 666 = 185308508093904
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.
689 : 1, 13, 53, 689
723 : 1, 3, 241, 723
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
629 : 1, 17, 37, 629
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,723,888,629,666, is 1.
Now, the common factors can be found like this.
689:13x 53
723:3x 241
888:2x 2x 2x 3x 37
629:17x 37
666:2x 3x 3x 37
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 37x 37 = 24642
Therefore, the value for common factors is 24642.
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 = 185308508093904/(1x24642)
LCM = 185308508093904/24642
LCM = 7520027112
Thus, we can understand that the LCM of 689,723,888,629,666 is 7520027112.
