Given numbers are 261,435,961,710,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,435,961,710,162 is 1602746190.
Find LCM of 261,435,961,710,162 with Prime Factorization
| 2 | 261, 435, 961, 710, 162 |
| 3 | 261, 435, 961, 355, 81 |
| 3 | 87, 145, 961, 355, 27 |
| 5 | 29, 145, 961, 355, 9 |
| 29 | 29, 29, 961, 71, 9 |
| 1, 1, 961, 71, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 29 x 1 x 1 x 961 x 71 x 9 = 1602746190
Therefore, the lowest common multiple of 261,435,961,710,162 is 1602746190.
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.
261 x 435 x 961 x 710 x 162 = 12549502667700
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.
261 : 1, 3, 9, 29, 87, 261
435 : 1, 3, 5, 15, 29, 87, 145, 435
961 : 1, 31, 961
710 : 1, 2, 5, 10, 71, 142, 355, 710
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,435,961,710,162, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
435:3x 5x 29
961:31x 31
710:2x 5x 71
162:2x 3x 3x 3x 3
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 3x 5x 29 = 7830
Therefore, the value for common factors is 7830.
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 = 12549502667700/(1x7830)
LCM = 12549502667700/7830
LCM = 1602746190
Thus, we can understand that the LCM of 261,435,961,710,162 is 1602746190.
