Given numbers are 856,548,778,548
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 856,548,778,548 is 45618808.
Find LCM of 856,548,778,548 with Prime Factorization
| 2 | 856, 548, 778, 548 |
| 2 | 428, 274, 389, 274 |
| 137 | 214, 137, 389, 137 |
| 214, 1, 389, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 137 x 214 x 1 x 389 x 1 = 45618808
Therefore, the lowest common multiple of 856,548,778,548 is 45618808.
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.
856 x 548 x 778 x 548 = 199992854272
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
548 : 1, 2, 4, 137, 274, 548
778 : 1, 2, 389, 778
548 : 1, 2, 4, 137, 274, 548
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,548,778,548, is 2.
Now, the common factors can be found like this.
856:2x 2x 2x 107
548:2x 2x 137
778:2x 389
548:2x 2x 137
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 137 = 2192
Therefore, the value for common factors is 2192.
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 = 199992854272/(2x2192)
LCM = 199992854272/4384
LCM = 45618808
Thus, we can understand that the LCM of 856,548,778,548 is 45618808.
