Given numbers are 772,958,286,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 772,958,286,338 is 687435892.
Find LCM of 772,958,286,338 with Prime Factorization
| 2 | 772, 958, 286, 338 |
| 13 | 386, 479, 143, 169 |
| 386, 479, 11, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 386 x 479 x 11 x 13 = 687435892
Therefore, the lowest common multiple of 772,958,286,338 is 687435892.
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.
772 x 958 x 286 x 338 = 71493332768
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.
772 : 1, 2, 4, 193, 386, 772
958 : 1, 2, 479, 958
286 : 1, 2, 11, 13, 22, 26, 143, 286
338 : 1, 2, 13, 26, 169, 338
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,958,286,338, is 2.
Now, the common factors can be found like this.
772:2x 2x 193
958:2x 479
286:2x 11x 13
338:2x 13x 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 13 = 52
Therefore, the value for common factors is 52.
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 = 71493332768/(2x52)
LCM = 71493332768/104
LCM = 687435892
Thus, we can understand that the LCM of 772,958,286,338 is 687435892.
