Given numbers are 646,614,410,925,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,614,410,925,390 is 293333112150.
Find LCM of 646,614,410,925,390 with Prime Factorization
| 2 | 646, 614, 410, 925, 390 |
| 5 | 323, 307, 205, 925, 195 |
| 323, 307, 41, 185, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 323 x 307 x 41 x 185 x 39 = 293333112150
Therefore, the lowest common multiple of 646,614,410,925,390 is 293333112150.
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.
646 x 614 x 410 x 925 x 390 = 58666622430000
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
614 : 1, 2, 307, 614
410 : 1, 2, 5, 10, 41, 82, 205, 410
925 : 1, 5, 25, 37, 185, 925
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,614,410,925,390, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
614:2x 307
410:2x 5x 41
925:5x 5x 37
390:2x 3x 5x 13
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 2x 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 58666622430000/(1x200)
LCM = 58666622430000/200
LCM = 293333112150
Thus, we can understand that the LCM of 646,614,410,925,390 is 293333112150.
