Given numbers are 268,689,705,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 268,689,705,611 is 130179660.
Find LCM of 268,689,705,611 with Prime Factorization
| 13 | 268, 689, 705, 611 |
| 47 | 268, 53, 705, 47 |
| 268, 53, 15, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 47 x 268 x 53 x 15 x 1 = 130179660
Therefore, the lowest common multiple of 268,689,705,611 is 130179660.
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.
268 x 689 x 705 x 611 = 79539772260
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.
268 : 1, 2, 4, 67, 134, 268
689 : 1, 13, 53, 689
705 : 1, 3, 5, 15, 47, 141, 235, 705
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 268,689,705,611, is 1.
Now, the common factors can be found like this.
268:2x 2x 67
689:13x 53
705:3x 5x 47
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.
13x 47 = 611
Therefore, the value for common factors is 611.
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 = 79539772260/(1x611)
LCM = 79539772260/611
LCM = 130179660
Thus, we can understand that the LCM of 268,689,705,611 is 130179660.
