Given numbers are 766,685,846,639,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,685,846,639,387 is 677620463490.
Find LCM of 766,685,846,639,387 with Prime Factorization
| 2 | 766, 685, 846, 639, 387 |
| 3 | 383, 685, 423, 639, 387 |
| 3 | 383, 685, 141, 213, 129 |
| 383, 685, 47, 71, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 383 x 685 x 47 x 71 x 43 = 677620463490
Therefore, the lowest common multiple of 766,685,846,639,387 is 677620463490.
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.
766 x 685 x 846 x 639 x 387 = 109774515085380
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.
766 : 1, 2, 383, 766
685 : 1, 5, 137, 685
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
639 : 1, 3, 9, 71, 213, 639
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,685,846,639,387, is 1.
Now, the common factors can be found like this.
766:2x 383
685:5x 137
846:2x 3x 3x 47
639:3x 3x 71
387:3x 3x 43
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 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 109774515085380/(1x162)
LCM = 109774515085380/162
LCM = 677620463490
Thus, we can understand that the LCM of 766,685,846,639,387 is 677620463490.
