Given numbers are 308,428,788,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 308,428,788,429 is 253200948.
Find LCM of 308,428,788,429 with Prime Factorization
| 2 | 308, 428, 788, 429 |
| 2 | 154, 214, 394, 429 |
| 11 | 77, 107, 197, 429 |
| 7, 107, 197, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 7 x 107 x 197 x 39 = 253200948
Therefore, the lowest common multiple of 308,428,788,429 is 253200948.
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.
308 x 428 x 788 x 429 = 44563366848
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
428 : 1, 2, 4, 107, 214, 428
788 : 1, 2, 4, 197, 394, 788
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,428,788,429, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
428:2x 2x 107
788:2x 2x 197
429:3x 11x 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 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 44563366848/(1x176)
LCM = 44563366848/176
LCM = 253200948
Thus, we can understand that the LCM of 308,428,788,429 is 253200948.
