Given numbers are 689,660,696,143,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,660,696,143,611 is 1239621240.
Find LCM of 689,660,696,143,611 with Prime Factorization
| 2 | 689, 660, 696, 143, 611 |
| 2 | 689, 330, 348, 143, 611 |
| 3 | 689, 165, 174, 143, 611 |
| 11 | 689, 55, 58, 143, 611 |
| 13 | 689, 5, 58, 13, 611 |
| 53, 5, 58, 1, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 53 x 5 x 58 x 1 x 47 = 1239621240
Therefore, the lowest common multiple of 689,660,696,143,611 is 1239621240.
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 660 x 696 x 143 x 611 = 27653470621920
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
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
143 : 1, 11, 13, 143
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,660,696,143,611, is 1.
Now, the common factors can be found like this.
689:13x 53
660:2x 2x 3x 5x 11
696:2x 2x 2x 3x 29
143:11x 13
611:13x 47
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 11x 13x 13 = 22308
Therefore, the value for common factors is 22308.
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 = 27653470621920/(1x22308)
LCM = 27653470621920/22308
LCM = 1239621240
Thus, we can understand that the LCM of 689,660,696,143,611 is 1239621240.
