Given numbers are 261,201,978,406,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,201,978,406,956 is 19074749652.
Find LCM of 261,201,978,406,956 with Prime Factorization
| 2 | 261, 201, 978, 406, 956 |
| 3 | 261, 201, 489, 203, 478 |
| 29 | 87, 67, 163, 203, 478 |
| 3, 67, 163, 7, 478 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 3 x 67 x 163 x 7 x 478 = 19074749652
Therefore, the lowest common multiple of 261,201,978,406,956 is 19074749652.
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 201 x 978 x 406 x 956 = 19914038636688
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
201 : 1, 3, 67, 201
978 : 1, 2, 3, 6, 163, 326, 489, 978
406 : 1, 2, 7, 14, 29, 58, 203, 406
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,201,978,406,956, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
201:3x 67
978:2x 3x 163
406:2x 7x 29
956:2x 2x 239
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 3x 29 = 1044
Therefore, the value for common factors is 1044.
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 = 19914038636688/(1x1044)
LCM = 19914038636688/1044
LCM = 19074749652
Thus, we can understand that the LCM of 261,201,978,406,956 is 19074749652.
