Given numbers are 421,285,586,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,285,586,779 is 2882759610.
Find LCM of 421,285,586,779 with Prime Factorization
| 19 | 421, 285, 586, 779 |
| 421, 15, 586, 41 |
Multiply the prime numbers at the bottom and the left side.
19 x 421 x 15 x 586 x 41 = 2882759610
Therefore, the lowest common multiple of 421,285,586,779 is 2882759610.
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 285 x 586 x 779 = 54772432590
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
285 : 1, 3, 5, 15, 19, 57, 95, 285
586 : 1, 2, 293, 586
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,285,586,779, is 1.
Now, the common factors can be found like this.
421:421
285:3x 5x 19
586:2x 293
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 54772432590/(1x19)
LCM = 54772432590/19
LCM = 2882759610
Thus, we can understand that the LCM of 421,285,586,779 is 2882759610.
