Given numbers are 418,298,981,631,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,298,981,631,455 is 17541725611410.
Find LCM of 418,298,981,631,455 with Prime Factorization
2 | 418, 298, 981, 631, 455 |
209, 149, 981, 631, 455 |
Multiply the prime numbers at the bottom and the left side.
2 x 209 x 149 x 981 x 631 x 455 = 17541725611410
Therefore, the lowest common multiple of 418,298,981,631,455 is 17541725611410.
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.
418 x 298 x 981 x 631 x 455 = 35083451222820
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
298 : 1, 2, 149, 298
981 : 1, 3, 9, 109, 327, 981
631 : 1, 631
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,298,981,631,455, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
298:2x 149
981:3x 3x 109
631:631
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 35083451222820/(1x2)
LCM = 35083451222820/2
LCM = 17541725611410
Thus, we can understand that the LCM of 418,298,981,631,455 is 17541725611410.
