Given numbers are 774,410,558,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 774,410,558,240 is 39350160.
Find LCM of 774,410,558,240 with Prime Factorization
| 2 | 774, 410, 558, 240 |
| 3 | 387, 205, 279, 120 |
| 3 | 129, 205, 93, 40 |
| 5 | 43, 205, 31, 40 |
| 43, 41, 31, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 43 x 41 x 31 x 8 = 39350160
Therefore, the lowest common multiple of 774,410,558,240 is 39350160.
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 410 x 558 x 240 = 42498172800
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
410 : 1, 2, 5, 10, 41, 82, 205, 410
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,410,558,240, is 2.
Now, the common factors can be found like this.
774:2x 3x 3x 43
410:2x 5x 41
558:2x 3x 3x 31
240:2x 2x 2x 2x 3x 5
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 3x 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 42498172800/(2x540)
LCM = 42498172800/1080
LCM = 39350160
Thus, we can understand that the LCM of 774,410,558,240 is 39350160.
