Given numbers are 754,902,561,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 754,902,561,806 is 537625374.
Find LCM of 754,902,561,806 with Prime Factorization
| 2 | 754, 902, 561, 806 |
| 11 | 377, 451, 561, 403 |
| 13 | 377, 41, 51, 403 |
| 29, 41, 51, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 29 x 41 x 51 x 31 = 537625374
Therefore, the lowest common multiple of 754,902,561,806 is 537625374.
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 902 x 561 x 806 = 307521713928
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
902 : 1, 2, 11, 22, 41, 82, 451, 902
561 : 1, 3, 11, 17, 33, 51, 187, 561
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,902,561,806, is 1.
Now, the common factors can be found like this.
754:2x 13x 29
902:2x 11x 41
561:3x 11x 17
806:2x 13x 31
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 11x 13 = 572
Therefore, the value for common factors is 572.
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 = 307521713928/(1x572)
LCM = 307521713928/572
LCM = 537625374
Thus, we can understand that the LCM of 754,902,561,806 is 537625374.
