Given numbers are 513,240,591,386,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 513,240,591,386,646 is 26526491280.
Find LCM of 513,240,591,386,646 with Prime Factorization
| 2 | 513, 240, 591, 386, 646 |
| 3 | 513, 120, 591, 193, 323 |
| 19 | 171, 40, 197, 193, 323 |
| 9, 40, 197, 193, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 9 x 40 x 197 x 193 x 17 = 26526491280
Therefore, the lowest common multiple of 513,240,591,386,646 is 26526491280.
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.
513 x 240 x 591 x 386 x 646 = 18144120035520
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
591 : 1, 3, 197, 591
386 : 1, 2, 193, 386
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,240,591,386,646, is 1.
Now, the common factors can be found like this.
513:3x 3x 3x 19
240:2x 2x 2x 2x 3x 5
591:3x 197
386:2x 193
646:2x 17x 19
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 3x 3x 19 = 684
Therefore, the value for common factors is 684.
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 = 18144120035520/(1x684)
LCM = 18144120035520/684
LCM = 26526491280
Thus, we can understand that the LCM of 513,240,591,386,646 is 26526491280.
