Given numbers are 655,120,494,192
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,120,494,192 is 31062720.
Find LCM of 655,120,494,192 with Prime Factorization
| 2 | 655, 120, 494, 192 |
| 2 | 655, 60, 247, 96 |
| 2 | 655, 30, 247, 48 |
| 3 | 655, 15, 247, 24 |
| 5 | 655, 5, 247, 8 |
| 131, 1, 247, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 131 x 1 x 247 x 8 = 31062720
Therefore, the lowest common multiple of 655,120,494,192 is 31062720.
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 120 x 494 x 192 = 7455052800
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
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
494 : 1, 2, 13, 19, 26, 38, 247, 494
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,120,494,192, is 1.
Now, the common factors can be found like this.
655:5x 131
120:2x 2x 2x 3x 5
494:2x 13x 19
192:2x 2x 2x 2x 2x 2x 3
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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 7455052800/(1x240)
LCM = 7455052800/240
LCM = 31062720
Thus, we can understand that the LCM of 655,120,494,192 is 31062720.
