Given numbers are 304,342,399,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 304,342,399,618 is 1972656.
Find LCM of 304,342,399,618 with Prime Factorization
| 2 | 304, 342, 399, 618 |
| 3 | 152, 171, 399, 309 |
| 19 | 152, 57, 133, 103 |
| 8, 3, 7, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 8 x 3 x 7 x 103 = 1972656
Therefore, the lowest common multiple of 304,342,399,618 is 1972656.
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.
304 x 342 x 399 x 618 = 25636637376
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.
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
399 : 1, 3, 7, 19, 21, 57, 133, 399
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 304,342,399,618, is 1.
Now, the common factors can be found like this.
304:2x 2x 2x 2x 19
342:2x 3x 3x 19
399:3x 7x 19
618:2x 3x 103
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 3x 3x 19x 19 = 12996
Therefore, the value for common factors is 12996.
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 = 25636637376/(1x12996)
LCM = 25636637376/12996
LCM = 1972656
Thus, we can understand that the LCM of 304,342,399,618 is 1972656.
