Find LCM of 684,685,358,906,780 with Prime Factorization
| 2 | 684, 685, 358, 906, 780 |
| 2 | 342, 685, 179, 453, 390 |
| 3 | 171, 685, 179, 453, 195 |
| 5 | 57, 685, 179, 151, 65 |
| 57, 137, 179, 151, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 57 x 137 x 179 x 151 x 13 = 164634179580
Therefore, the lowest common multiple of 684,685,358,906,780 is 164634179580.
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.
684 x 685 x 358 x 906 x 780 = 118536609297600
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
685 : 1, 5, 137, 685
358 : 1, 2, 179, 358
906 : 1, 2, 3, 6, 151, 302, 453, 906
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,685,358,906,780, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
685:5x 137
358:2x 179
906:2x 3x 151
780:2x 2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 118536609297600/(1x720)
LCM = 118536609297600/720
LCM = 164634179580
Thus, we can understand that the LCM of 684,685,358,906,780 is 164634179580.
