Given numbers are 774,612,576,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 774,612,576,905 is 381055680.
Find LCM of 774,612,576,905 with Prime Factorization
| 2 | 774, 612, 576, 905 |
| 2 | 387, 306, 288, 905 |
| 3 | 387, 153, 144, 905 |
| 3 | 129, 51, 48, 905 |
| 43, 17, 16, 905 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 43 x 17 x 16 x 905 = 381055680
Therefore, the lowest common multiple of 774,612,576,905 is 381055680.
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 612 x 576 x 905 = 246924080640
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
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,612,576,905, is 1.
Now, the common factors can be found like this.
774:2x 3x 3x 43
612:2x 2x 3x 3x 17
576:2x 2x 2x 2x 2x 2x 3x 3
905:5x 181
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 3x 3 = 648
Therefore, the value for common factors is 648.
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 = 246924080640/(1x648)
LCM = 246924080640/648
LCM = 381055680
Thus, we can understand that the LCM of 774,612,576,905 is 381055680.
