Given numbers are 812,686,668,718,793
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,686,668,718,793 is 1891630101452.
Find LCM of 812,686,668,718,793 with Prime Factorization
| 2 | 812, 686, 668, 718, 793 |
| 2 | 406, 343, 334, 359, 793 |
| 7 | 203, 343, 167, 359, 793 |
| 29, 49, 167, 359, 793 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 29 x 49 x 167 x 359 x 793 = 1891630101452
Therefore, the lowest common multiple of 812,686,668,718,793 is 1891630101452.
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.
812 x 686 x 668 x 718 x 793 = 211862571362624
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
686 : 1, 2, 7, 14, 49, 98, 343, 686
668 : 1, 2, 4, 167, 334, 668
718 : 1, 2, 359, 718
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,686,668,718,793, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
686:2x 7x 7x 7
668:2x 2x 167
718:2x 359
793:13x 61
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 7 = 112
Therefore, the value for common factors is 112.
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 = 211862571362624/(1x112)
LCM = 211862571362624/112
LCM = 1891630101452
Thus, we can understand that the LCM of 812,686,668,718,793 is 1891630101452.
