Given numbers are 490,672,838,841
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 490,672,838,841 is 8287954080.
Find LCM of 490,672,838,841 with Prime Factorization
| 2 | 490, 672, 838, 841 |
| 7 | 245, 336, 419, 841 |
| 35, 48, 419, 841 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 35 x 48 x 419 x 841 = 8287954080
Therefore, the lowest common multiple of 490,672,838,841 is 8287954080.
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.
490 x 672 x 838 x 841 = 232062714240
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.
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
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
838 : 1, 2, 419, 838
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,672,838,841, is 1.
Now, the common factors can be found like this.
490:2x 5x 7x 7
672:2x 2x 2x 2x 2x 3x 7
838:2x 419
841:29x 29
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 7 = 28
Therefore, the value for common factors is 28.
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 = 232062714240/(1x28)
LCM = 232062714240/28
LCM = 8287954080
Thus, we can understand that the LCM of 490,672,838,841 is 8287954080.
