Given numbers are 774,819,782,978,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 774,819,782,978,902 is 2024525525022.
Find LCM of 774,819,782,978,902 with Prime Factorization
| 2 | 774, 819, 782, 978, 902 |
| 3 | 387, 819, 391, 489, 451 |
| 3 | 129, 273, 391, 163, 451 |
| 43, 91, 391, 163, 451 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 43 x 91 x 391 x 163 x 451 = 2024525525022
Therefore, the lowest common multiple of 774,819,782,978,902 is 2024525525022.
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.
774 x 819 x 782 x 978 x 902 = 437297513404752
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.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
782 : 1, 2, 17, 23, 34, 46, 391, 782
978 : 1, 2, 3, 6, 163, 326, 489, 978
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,819,782,978,902, is 1.
Now, the common factors can be found like this.
774:2x 3x 3x 43
819:3x 3x 7x 13
782:2x 17x 23
978:2x 3x 163
902:2x 11x 41
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 437297513404752/(1x216)
LCM = 437297513404752/216
LCM = 2024525525022
Thus, we can understand that the LCM of 774,819,782,978,902 is 2024525525022.
