Given numbers are 764,821,836,806,248
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 764,821,836,806,248 is 105661760776.
Find LCM of 764,821,836,806,248 with Prime Factorization
| 2 | 764, 821, 836, 806, 248 |
| 2 | 382, 821, 418, 403, 124 |
| 31 | 191, 821, 209, 403, 62 |
| 191, 821, 209, 13, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 191 x 821 x 209 x 13 x 2 = 105661760776
Therefore, the lowest common multiple of 764,821,836,806,248 is 105661760776.
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.
764 x 821 x 836 x 806 x 248 = 104816466689792
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.
764 : 1, 2, 4, 191, 382, 764
821 : 1, 821
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
806 : 1, 2, 13, 26, 31, 62, 403, 806
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,821,836,806,248, is 1.
Now, the common factors can be found like this.
764:2x 2x 191
821:821
836:2x 2x 11x 19
806:2x 13x 31
248:2x 2x 2x 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 2x 2x 2x 31 = 992
Therefore, the value for common factors is 992.
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 = 104816466689792/(1x992)
LCM = 104816466689792/992
LCM = 105661760776
Thus, we can understand that the LCM of 764,821,836,806,248 is 105661760776.
