Given numbers are 611,806,868,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 611,806,868,155 is 2651740.
Find LCM of 611,806,868,155 with Prime Factorization
| 2 | 611, 806, 868, 155 |
| 13 | 611, 403, 434, 155 |
| 31 | 47, 31, 434, 155 |
| 47, 1, 14, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 31 x 47 x 1 x 14 x 5 = 2651740
Therefore, the lowest common multiple of 611,806,868,155 is 2651740.
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.
611 x 806 x 868 x 155 = 66256375640
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.
611 : 1, 13, 47, 611
806 : 1, 2, 13, 26, 31, 62, 403, 806
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,806,868,155, is 1.
Now, the common factors can be found like this.
611:13x 47
806:2x 13x 31
868:2x 2x 7x 31
155:5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 31x 31 = 24986
Therefore, the value for common factors is 24986.
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 = 66256375640/(1x24986)
LCM = 66256375640/24986
LCM = 2651740
Thus, we can understand that the LCM of 611,806,868,155 is 2651740.
