Given numbers are 657,391,790,494,657
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,391,790,494,657 is 50126360310.
Find LCM of 657,391,790,494,657 with Prime Factorization
| 2 | 657, 391, 790, 494, 657 |
| 3 | 657, 391, 395, 247, 657 |
| 3 | 219, 391, 395, 247, 219 |
| 73 | 73, 391, 395, 247, 73 |
| 1, 391, 395, 247, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 73 x 1 x 391 x 395 x 247 x 1 = 50126360310
Therefore, the lowest common multiple of 657,391,790,494,657 is 50126360310.
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.
657 x 391 x 790 x 494 x 657 = 65866037447340
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.
657 : 1, 3, 9, 73, 219, 657
391 : 1, 17, 23, 391
790 : 1, 2, 5, 10, 79, 158, 395, 790
494 : 1, 2, 13, 19, 26, 38, 247, 494
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,391,790,494,657, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
391:17x 23
790:2x 5x 79
494:2x 13x 19
657:3x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 73 = 1314
Therefore, the value for common factors is 1314.
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 = 65866037447340/(1x1314)
LCM = 65866037447340/1314
LCM = 50126360310
Thus, we can understand that the LCM of 657,391,790,494,657 is 50126360310.
