Given numbers are 686,772,718,386
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,772,718,386 is 95061764.
Find LCM of 686,772,718,386 with Prime Factorization
| 2 | 686, 772, 718, 386 |
| 193 | 343, 386, 359, 193 |
| 343, 2, 359, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 193 x 343 x 2 x 359 x 1 = 95061764
Therefore, the lowest common multiple of 686,772,718,386 is 95061764.
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 772 x 718 x 386 = 146775363616
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
772 : 1, 2, 4, 193, 386, 772
718 : 1, 2, 359, 718
386 : 1, 2, 193, 386
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,772,718,386, is 2.
Now, the common factors can be found like this.
686:2x 7x 7x 7
772:2x 2x 193
718:2x 359
386:2x 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 2x 193 = 772
Therefore, the value for common factors is 772.
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 = 146775363616/(2x772)
LCM = 146775363616/1544
LCM = 95061764
Thus, we can understand that the LCM of 686,772,718,386 is 95061764.
