Given numbers are 686,626,812,286,539
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,626,812,286,539 is 1780871092.
Find LCM of 686,626,812,286,539 with Prime Factorization
| 2 | 686, 626, 812, 286, 539 |
| 7 | 343, 313, 406, 143, 539 |
| 7 | 49, 313, 58, 143, 77 |
| 11 | 7, 313, 58, 143, 11 |
| 7, 313, 58, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 11 x 7 x 313 x 58 x 13 x 1 = 1780871092
Therefore, the lowest common multiple of 686,626,812,286,539 is 1780871092.
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.
686 x 626 x 812 x 286 x 539 = 53753813040928
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
626 : 1, 2, 313, 626
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
286 : 1, 2, 11, 13, 22, 26, 143, 286
539 : 1, 7, 11, 49, 77, 539
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,626,812,286,539, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
626:2x 313
812:2x 2x 7x 29
286:2x 11x 13
539:7x 7x 11
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 7x 7x 7x 11 = 30184
Therefore, the value for common factors is 30184.
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 = 53753813040928/(1x30184)
LCM = 53753813040928/30184
LCM = 1780871092
Thus, we can understand that the LCM of 686,626,812,286,539 is 1780871092.
