Given numbers are 386,772,188,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 386,772,188,308 is 2793868.
Find LCM of 386,772,188,308 with Prime Factorization
| 2 | 386, 772, 188, 308 |
| 2 | 193, 386, 94, 154 |
| 193 | 193, 193, 47, 77 |
| 1, 1, 47, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 193 x 1 x 1 x 47 x 77 = 2793868
Therefore, the lowest common multiple of 386,772,188,308 is 2793868.
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.
386 x 772 x 188 x 308 = 17254928768
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.
386 : 1, 2, 193, 386
772 : 1, 2, 4, 193, 386, 772
188 : 1, 2, 4, 47, 94, 188
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,772,188,308, is 2.
Now, the common factors can be found like this.
386:2x 193
772:2x 2x 193
188:2x 2x 47
308:2x 2x 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 2x 193 = 3088
Therefore, the value for common factors is 3088.
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 = 17254928768/(2x3088)
LCM = 17254928768/6176
LCM = 2793868
Thus, we can understand that the LCM of 386,772,188,308 is 2793868.
