Given numbers are 409,497,911,818,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,497,911,818,490 is 12962719210.
Find LCM of 409,497,911,818,490 with Prime Factorization
| 2 | 409, 497, 911, 818, 490 |
| 7 | 409, 497, 911, 409, 245 |
| 409 | 409, 71, 911, 409, 35 |
| 1, 71, 911, 1, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 409 x 1 x 71 x 911 x 1 x 35 = 12962719210
Therefore, the lowest common multiple of 409,497,911,818,490 is 12962719210.
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.
409 x 497 x 911 x 818 x 490 = 74224530196460
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.
409 : 1, 409
497 : 1, 7, 71, 497
911 : 1, 911
818 : 1, 2, 409, 818
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,497,911,818,490, is 1.
Now, the common factors can be found like this.
409:409
497:7x 71
911:911
818:2x 409
490:2x 5x 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 7x 409 = 5726
Therefore, the value for common factors is 5726.
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 = 74224530196460/(1x5726)
LCM = 74224530196460/5726
LCM = 12962719210
Thus, we can understand that the LCM of 409,497,911,818,490 is 12962719210.
