Given numbers are 655,638,262,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,638,262,261 is 3761010.
Find LCM of 655,638,262,261 with Prime Factorization
| 2 | 655, 638, 262, 261 |
| 29 | 655, 319, 131, 261 |
| 131 | 655, 11, 131, 9 |
| 5, 11, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 131 x 5 x 11 x 1 x 9 = 3761010
Therefore, the lowest common multiple of 655,638,262,261 is 3761010.
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.
655 x 638 x 262 x 261 = 28576153980
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.
655 : 1, 5, 131, 655
638 : 1, 2, 11, 22, 29, 58, 319, 638
262 : 1, 2, 131, 262
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,638,262,261, is 1.
Now, the common factors can be found like this.
655:5x 131
638:2x 11x 29
262:2x 131
261:3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 29x 131 = 7598
Therefore, the value for common factors is 7598.
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 = 28576153980/(1x7598)
LCM = 28576153980/7598
LCM = 3761010
Thus, we can understand that the LCM of 655,638,262,261 is 3761010.
