Given numbers are 778,548,905,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,548,905,284 is 13697366860.
Find LCM of 778,548,905,284 with Prime Factorization
| 2 | 778, 548, 905, 284 |
| 2 | 389, 274, 905, 142 |
| 389, 137, 905, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 389 x 137 x 905 x 71 = 13697366860
Therefore, the lowest common multiple of 778,548,905,284 is 13697366860.
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 548 x 905 x 284 = 109578934880
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
548 : 1, 2, 4, 137, 274, 548
905 : 1, 5, 181, 905
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,548,905,284, is 1.
Now, the common factors can be found like this.
778:2x 389
548:2x 2x 137
905:5x 181
284:2x 2x 71
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 2 = 8
Therefore, the value for common factors is 8.
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 = 109578934880/(1x8)
LCM = 109578934880/8
LCM = 13697366860
Thus, we can understand that the LCM of 778,548,905,284 is 13697366860.
