Given numbers are 619,312,285,845,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,312,285,845,771 is 61297861560.
Find LCM of 619,312,285,845,771 with Prime Factorization
| 3 | 619, 312, 285, 845, 771 |
| 5 | 619, 104, 95, 845, 257 |
| 13 | 619, 104, 19, 169, 257 |
| 619, 8, 19, 13, 257 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 619 x 8 x 19 x 13 x 257 = 61297861560
Therefore, the lowest common multiple of 619,312,285,845,771 is 61297861560.
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.
619 x 312 x 285 x 845 x 771 = 35859249012600
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.
619 : 1, 619
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
285 : 1, 3, 5, 15, 19, 57, 95, 285
845 : 1, 5, 13, 65, 169, 845
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,312,285,845,771, is 1.
Now, the common factors can be found like this.
619:619
312:2x 2x 2x 3x 13
285:3x 5x 19
845:5x 13x 13
771:3x 257
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 5x 13 = 585
Therefore, the value for common factors is 585.
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 = 35859249012600/(1x585)
LCM = 35859249012600/585
LCM = 61297861560
Thus, we can understand that the LCM of 619,312,285,845,771 is 61297861560.
