Given numbers are 671,747,171,977,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,747,171,977,261 is 269829410499.
Find LCM of 671,747,171,977,261 with Prime Factorization
| 3 | 671, 747, 171, 977, 261 |
| 3 | 671, 249, 57, 977, 87 |
| 671, 83, 19, 977, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 671 x 83 x 19 x 977 x 29 = 269829410499
Therefore, the lowest common multiple of 671,747,171,977,261 is 269829410499.
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.
671 x 747 x 171 x 977 x 261 = 21856182250419
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.
671 : 1, 11, 61, 671
747 : 1, 3, 9, 83, 249, 747
171 : 1, 3, 9, 19, 57, 171
977 : 1, 977
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 671,747,171,977,261, is 1.
Now, the common factors can be found like this.
671:11x 61
747:3x 3x 83
171:3x 3x 19
977:977
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.
3x 3x 3x 3 = 81
Therefore, the value for common factors is 81.
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 = 21856182250419/(1x81)
LCM = 21856182250419/81
LCM = 269829410499
Thus, we can understand that the LCM of 671,747,171,977,261 is 269829410499.
