Given numbers are 304,574,646,618,906
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 304,574,646,618,906 is 69205375344.
Find LCM of 304,574,646,618,906 with Prime Factorization
| 2 | 304, 574, 646, 618, 906 |
| 3 | 152, 287, 323, 309, 453 |
| 19 | 152, 287, 323, 103, 151 |
| 8, 287, 17, 103, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 8 x 287 x 17 x 103 x 151 = 69205375344
Therefore, the lowest common multiple of 304,574,646,618,906 is 69205375344.
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 574 x 646 x 618 x 906 = 63115302313728
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
574 : 1, 2, 7, 14, 41, 82, 287, 574
646 : 1, 2, 17, 19, 34, 38, 323, 646
618 : 1, 2, 3, 6, 103, 206, 309, 618
906 : 1, 2, 3, 6, 151, 302, 453, 906
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 304,574,646,618,906, is 2.
Now, the common factors can be found like this.
304:2x 2x 2x 2x 19
574:2x 7x 41
646:2x 17x 19
618:2x 3x 103
906:2x 3x 151
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 3x 19 = 456
Therefore, the value for common factors is 456.
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 = 63115302313728/(2x456)
LCM = 63115302313728/912
LCM = 69205375344
Thus, we can understand that the LCM of 304,574,646,618,906 is 69205375344.
