Given numbers are 655,736,506,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,736,506,393 is 15908640.
Find LCM of 655,736,506,393 with Prime Factorization
| 2 | 655, 736, 506, 393 |
| 23 | 655, 368, 253, 393 |
| 131 | 655, 16, 11, 393 |
| 5, 16, 11, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 131 x 5 x 16 x 11 x 3 = 15908640
Therefore, the lowest common multiple of 655,736,506,393 is 15908640.
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.
655 x 736 x 506 x 393 = 95865464640
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.
655 : 1, 5, 131, 655
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
506 : 1, 2, 11, 22, 23, 46, 253, 506
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,736,506,393, is 1.
Now, the common factors can be found like this.
655:5x 131
736:2x 2x 2x 2x 2x 23
506:2x 11x 23
393:3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23x 131 = 6026
Therefore, the value for common factors is 6026.
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 = 95865464640/(1x6026)
LCM = 95865464640/6026
LCM = 15908640
Thus, we can understand that the LCM of 655,736,506,393 is 15908640.
