Given numbers are 418,947,623,770,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,947,623,770,806 is 496923296870.
Find LCM of 418,947,623,770,806 with Prime Factorization
| 2 | 418, 947, 623, 770, 806 |
| 7 | 209, 947, 623, 385, 403 |
| 11 | 209, 947, 89, 55, 403 |
| 19, 947, 89, 5, 403 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 19 x 947 x 89 x 5 x 403 = 496923296870
Therefore, the lowest common multiple of 418,947,623,770,806 is 496923296870.
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 947 x 623 x 770 x 806 = 153052375435960
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
947 : 1, 947
623 : 1, 7, 89, 623
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
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 418,947,623,770,806, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
947:947
623:7x 89
770:2x 5x 7x 11
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 7x 11 = 308
Therefore, the value for common factors is 308.
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 = 153052375435960/(1x308)
LCM = 153052375435960/308
LCM = 496923296870
Thus, we can understand that the LCM of 418,947,623,770,806 is 496923296870.
