Given numbers are 421,204,898,974,449
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,204,898,974,449 is 18779653092.
Find LCM of 421,204,898,974,449 with Prime Factorization
2 | 421, 204, 898, 974, 449 |
449 | 421, 102, 449, 487, 449 |
421, 102, 1, 487, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 449 x 421 x 102 x 1 x 487 x 1 = 18779653092
Therefore, the lowest common multiple of 421,204,898,974,449 is 18779653092.
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.
421 x 204 x 898 x 974 x 449 = 33728256953232
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.
421 : 1, 421
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
898 : 1, 2, 449, 898
974 : 1, 2, 487, 974
449 : 1, 449
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,204,898,974,449, is 1.
Now, the common factors can be found like this.
421:421
204:2x 2x 3x 17
898:2x 449
974:2x 487
449:449
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 449 = 1796
Therefore, the value for common factors is 1796.
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 = 33728256953232/(1x1796)
LCM = 33728256953232/1796
LCM = 18779653092
Thus, we can understand that the LCM of 421,204,898,974,449 is 18779653092.
