The LCM of 342,570,655,898 is 100580490.
Find LCM of 342,570,655,898 with Prime Factorization
| 2 | 342, 570, 655, 898 |
| 3 | 171, 285, 655, 449 |
| 5 | 57, 95, 655, 449 |
| 19 | 57, 19, 131, 449 |
| 3, 1, 131, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 3 x 1 x 131 x 449 = 100580490
Therefore, the lowest common multiple of 342,570,655,898 is 100580490.
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.
342 x 570 x 655 x 898 = 114661758600
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
655 : 1, 5, 131, 655
898 : 1, 2, 449, 898
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,570,655,898, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
570:2x 3x 5x 19
655:5x 131
898:2x 449
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 5x 19 = 1140
Therefore, the value for common factors is 1140.
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 = 114661758600/(1x1140)
LCM = 114661758600/1140
LCM = 100580490
Thus, we can understand that the LCM of 342,570,655,898 is 100580490.
