Given numbers are 781,204,351,345,341
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,204,351,345,341 is 66454837020.
Find LCM of 781,204,351,345,341 with Prime Factorization
| 3 | 781, 204, 351, 345, 341 |
| 11 | 781, 68, 117, 115, 341 |
| 71, 68, 117, 115, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 71 x 68 x 117 x 115 x 31 = 66454837020
Therefore, the lowest common multiple of 781,204,351,345,341 is 66454837020.
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.
781 x 204 x 351 x 345 x 341 = 6579028864980
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.
781 : 1, 11, 71, 781
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
351 : 1, 3, 9, 13, 27, 39, 117, 351
345 : 1, 3, 5, 15, 23, 69, 115, 345
341 : 1, 11, 31, 341
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,204,351,345,341, is 1.
Now, the common factors can be found like this.
781:11x 71
204:2x 2x 3x 17
351:3x 3x 3x 13
345:3x 5x 23
341:11x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11 = 99
Therefore, the value for common factors is 99.
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 = 6579028864980/(1x99)
LCM = 6579028864980/99
LCM = 66454837020
Thus, we can understand that the LCM of 781,204,351,345,341 is 66454837020.
