Given numbers are 754,806,572,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 754,806,572,981 is 504457668.
Find LCM of 754,806,572,981 with Prime Factorization
2 | 754, 806, 572, 981 |
13 | 377, 403, 286, 981 |
29, 31, 22, 981 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 29 x 31 x 22 x 981 = 504457668
Therefore, the lowest common multiple of 754,806,572,981 is 504457668.
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.
754 x 806 x 572 x 981 = 341013383568
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.
754 : 1, 2, 13, 26, 29, 58, 377, 754
806 : 1, 2, 13, 26, 31, 62, 403, 806
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,806,572,981, is 1.
Now, the common factors can be found like this.
754:2x 13x 29
806:2x 13x 31
572:2x 2x 11x 13
981:3x 3x 109
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 13x 13 = 676
Therefore, the value for common factors is 676.
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 = 341013383568/(1x676)
LCM = 341013383568/676
LCM = 504457668
Thus, we can understand that the LCM of 754,806,572,981 is 504457668.
