Given numbers are 981,460,490,403,266
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,460,490,403,266 is 169309593180.
Find LCM of 981,460,490,403,266 with Prime Factorization
| 2 | 981, 460, 490, 403, 266 |
| 5 | 981, 230, 245, 403, 133 |
| 7 | 981, 46, 49, 403, 133 |
| 981, 46, 7, 403, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 981 x 46 x 7 x 403 x 19 = 169309593180
Therefore, the lowest common multiple of 981,460,490,403,266 is 169309593180.
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.
981 x 460 x 490 x 403 x 266 = 23703343045200
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.
981 : 1, 3, 9, 109, 327, 981
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
403 : 1, 13, 31, 403
266 : 1, 2, 7, 14, 19, 38, 133, 266
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,460,490,403,266, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
460:2x 2x 5x 23
490:2x 5x 7x 7
403:13x 31
266:2x 7x 19
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 23703343045200/(1x140)
LCM = 23703343045200/140
LCM = 169309593180
Thus, we can understand that the LCM of 981,460,490,403,266 is 169309593180.
