Given numbers are 781,445,330,104,965
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,445,330,104,965 is 20927769720.
Find LCM of 781,445,330,104,965 with Prime Factorization
| 2 | 781, 445, 330, 104, 965 |
| 5 | 781, 445, 165, 52, 965 |
| 11 | 781, 89, 33, 52, 193 |
| 71, 89, 3, 52, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 71 x 89 x 3 x 52 x 193 = 20927769720
Therefore, the lowest common multiple of 781,445,330,104,965 is 20927769720.
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 445 x 330 x 104 x 965 = 11510273346000
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
445 : 1, 5, 89, 445
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
104 : 1, 2, 4, 8, 13, 26, 52, 104
965 : 1, 5, 193, 965
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,445,330,104,965, is 1.
Now, the common factors can be found like this.
781:11x 71
445:5x 89
330:2x 3x 5x 11
104:2x 2x 2x 13
965:5x 193
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 11 = 550
Therefore, the value for common factors is 550.
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 = 11510273346000/(1x550)
LCM = 11510273346000/550
LCM = 20927769720
Thus, we can understand that the LCM of 781,445,330,104,965 is 20927769720.
