Given numbers are 655,442,646,385,115
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,442,646,385,115 is 9741721990.
Find LCM of 655,442,646,385,115 with Prime Factorization
| 2 | 655, 442, 646, 385, 115 |
| 5 | 655, 221, 323, 385, 115 |
| 17 | 131, 221, 323, 77, 23 |
| 131, 13, 19, 77, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 131 x 13 x 19 x 77 x 23 = 9741721990
Therefore, the lowest common multiple of 655,442,646,385,115 is 9741721990.
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 442 x 646 x 385 x 115 = 8280463691500
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
442 : 1, 2, 13, 17, 26, 34, 221, 442
646 : 1, 2, 17, 19, 34, 38, 323, 646
385 : 1, 5, 7, 11, 35, 55, 77, 385
115 : 1, 5, 23, 115
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,442,646,385,115, is 1.
Now, the common factors can be found like this.
655:5x 131
442:2x 13x 17
646:2x 17x 19
385:5x 7x 11
115:5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 17 = 850
Therefore, the value for common factors is 850.
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 = 8280463691500/(1x850)
LCM = 8280463691500/850
LCM = 9741721990
Thus, we can understand that the LCM of 655,442,646,385,115 is 9741721990.
