Given numbers are 548,546,768,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 548,546,768,389 is 3724541184.
Find LCM of 548,546,768,389 with Prime Factorization
| 2 | 548, 546, 768, 389 |
| 2 | 274, 273, 384, 389 |
| 3 | 137, 273, 192, 389 |
| 137, 91, 64, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 137 x 91 x 64 x 389 = 3724541184
Therefore, the lowest common multiple of 548,546,768,389 is 3724541184.
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.
548 x 546 x 768 x 389 = 89388988416
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.
548 : 1, 2, 4, 137, 274, 548
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 548,546,768,389, is 1.
Now, the common factors can be found like this.
548:2x 2x 137
546:2x 3x 7x 13
768:2x 2x 2x 2x 2x 2x 2x 2x 3
389:389
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 3 = 24
Therefore, the value for common factors is 24.
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 = 89388988416/(1x24)
LCM = 89388988416/24
LCM = 3724541184
Thus, we can understand that the LCM of 548,546,768,389 is 3724541184.
