Given numbers are 404,306,504,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 404,306,504,646 is 16441992.
Find LCM of 404,306,504,646 with Prime Factorization
2 | 404, 306, 504, 646 |
2 | 202, 153, 252, 323 |
3 | 101, 153, 126, 323 |
3 | 101, 51, 42, 323 |
17 | 101, 17, 14, 323 |
101, 1, 14, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 17 x 101 x 1 x 14 x 19 = 16441992
Therefore, the lowest common multiple of 404,306,504,646 is 16441992.
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.
404 x 306 x 504 x 646 = 40249996416
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.
404 : 1, 2, 4, 101, 202, 404
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
646 : 1, 2, 17, 19, 34, 38, 323, 646
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 404,306,504,646, is 2.
Now, the common factors can be found like this.
404:2x 2x 101
306:2x 3x 3x 17
504:2x 2x 2x 3x 3x 7
646:2x 17x 19
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 3x 17 = 1224
Therefore, the value for common factors is 1224.
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 = 40249996416/(2x1224)
LCM = 40249996416/2448
LCM = 16441992
Thus, we can understand that the LCM of 404,306,504,646 is 16441992.
