Given numbers are 423,418,380,813,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,418,380,813,129 is 20604135420.
Find LCM of 423,418,380,813,129 with Prime Factorization
2 | 423, 418, 380, 813, 129 |
3 | 423, 209, 190, 813, 129 |
19 | 141, 209, 190, 271, 43 |
141, 11, 10, 271, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 141 x 11 x 10 x 271 x 43 = 20604135420
Therefore, the lowest common multiple of 423,418,380,813,129 is 20604135420.
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.
423 x 418 x 380 x 813 x 129 = 7046614313640
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.
423 : 1, 3, 9, 47, 141, 423
418 : 1, 2, 11, 19, 22, 38, 209, 418
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
813 : 1, 3, 271, 813
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,418,380,813,129, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
418:2x 11x 19
380:2x 2x 5x 19
813:3x 271
129:3x 43
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 19 = 342
Therefore, the value for common factors is 342.
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 = 7046614313640/(1x342)
LCM = 7046614313640/342
LCM = 20604135420
Thus, we can understand that the LCM of 423,418,380,813,129 is 20604135420.
