Given numbers are 490,404,261,507,306
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 490,404,261,507,306 is 74220449940.
Find LCM of 490,404,261,507,306 with Prime Factorization
| 2 | 490, 404, 261, 507, 306 |
| 3 | 245, 202, 261, 507, 153 |
| 3 | 245, 202, 87, 169, 51 |
| 245, 202, 29, 169, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 245 x 202 x 29 x 169 x 17 = 74220449940
Therefore, the lowest common multiple of 490,404,261,507,306 is 74220449940.
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 404 x 261 x 507 x 306 = 8015808593520
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
404 : 1, 2, 4, 101, 202, 404
261 : 1, 3, 9, 29, 87, 261
507 : 1, 3, 13, 39, 169, 507
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,404,261,507,306, is 1.
Now, the common factors can be found like this.
490:2x 5x 7x 7
404:2x 2x 101
261:3x 3x 29
507:3x 13x 13
306:2x 3x 3x 17
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 8015808593520/(1x108)
LCM = 8015808593520/108
LCM = 74220449940
Thus, we can understand that the LCM of 490,404,261,507,306 is 74220449940.
