Given numbers are 418,321,446,486,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,321,446,486,391 is 947649970674.
Find LCM of 418,321,446,486,391 with Prime Factorization
2 | 418, 321, 446, 486, 391 |
3 | 209, 321, 223, 243, 391 |
209, 107, 223, 81, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 209 x 107 x 223 x 81 x 391 = 947649970674
Therefore, the lowest common multiple of 418,321,446,486,391 is 947649970674.
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 321 x 446 x 486 x 391 = 11371799648088
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
321 : 1, 3, 107, 321
446 : 1, 2, 223, 446
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,321,446,486,391, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
321:3x 107
446:2x 223
486:2x 3x 3x 3x 3x 3
391:17x 23
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 3 = 12
Therefore, the value for common factors is 12.
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 = 11371799648088/(1x12)
LCM = 11371799648088/12
LCM = 947649970674
Thus, we can understand that the LCM of 418,321,446,486,391 is 947649970674.
