Given numbers are 497,904,672,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 497,904,672,686 is 264181344.
Find LCM of 497,904,672,686 with Prime Factorization
| 2 | 497, 904, 672, 686 |
| 2 | 497, 452, 336, 343 |
| 2 | 497, 226, 168, 343 |
| 7 | 497, 113, 84, 343 |
| 71, 113, 12, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 71 x 113 x 12 x 49 = 264181344
Therefore, the lowest common multiple of 497,904,672,686 is 264181344.
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.
497 x 904 x 672 x 686 = 207118173696
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.
497 : 1, 7, 71, 497
904 : 1, 2, 4, 8, 113, 226, 452, 904
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
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 497,904,672,686, is 1.
Now, the common factors can be found like this.
497:7x 71
904:2x 2x 2x 113
672:2x 2x 2x 2x 2x 3x 7
686:2x 7x 7x 7
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 7x 7 = 784
Therefore, the value for common factors is 784.
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 = 207118173696/(1x784)
LCM = 207118173696/784
LCM = 264181344
Thus, we can understand that the LCM of 497,904,672,686 is 264181344.
