The LCM of 404,210,452,672,643 is 24657558240.
Find LCM of 404,210,452,672,643 with Prime Factorization
| 2 | 404, 210, 452, 672, 643 |
| 2 | 202, 105, 226, 336, 643 |
| 3 | 101, 105, 113, 168, 643 |
| 7 | 101, 35, 113, 56, 643 |
| 101, 5, 113, 8, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 101 x 5 x 113 x 8 x 643 = 24657558240
Therefore, the lowest common multiple of 404,210,452,672,643 is 24657558240.
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 210 x 452 x 672 x 643 = 16569879137280
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
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
452 : 1, 2, 4, 113, 226, 452
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 404,210,452,672,643, is 1.
Now, the common factors can be found like this.
404:2x 2x 101
210:2x 3x 5x 7
452:2x 2x 113
672:2x 2x 2x 2x 2x 3x 7
643:643
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 2x 3x 7 = 672
Therefore, the value for common factors is 672.
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 = 16569879137280/(1x672)
LCM = 16569879137280/672
LCM = 24657558240
Thus, we can understand that the LCM of 404,210,452,672,643 is 24657558240.
