Given numbers are 778,897,986,297,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,897,986,297,731 is 1464612072066.
Find LCM of 778,897,986,297,731 with Prime Factorization
| 2 | 778, 897, 986, 297, 731 |
| 3 | 389, 897, 493, 297, 731 |
| 17 | 389, 299, 493, 99, 731 |
| 389, 299, 29, 99, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 389 x 299 x 29 x 99 x 43 = 1464612072066
Therefore, the lowest common multiple of 778,897,986,297,731 is 1464612072066.
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.
778 x 897 x 986 x 297 x 731 = 149390431350732
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.
778 : 1, 2, 389, 778
897 : 1, 3, 13, 23, 39, 69, 299, 897
986 : 1, 2, 17, 29, 34, 58, 493, 986
297 : 1, 3, 9, 11, 27, 33, 99, 297
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,897,986,297,731, is 1.
Now, the common factors can be found like this.
778:2x 389
897:3x 13x 23
986:2x 17x 29
297:3x 3x 3x 11
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 149390431350732/(1x102)
LCM = 149390431350732/102
LCM = 1464612072066
Thus, we can understand that the LCM of 778,897,986,297,731 is 1464612072066.
