The LCM of 774,547,738,432 is 416603952.
Find LCM of 774,547,738,432 with Prime Factorization
| 2 | 774, 547, 738, 432 |
| 3 | 387, 547, 369, 216 |
| 3 | 129, 547, 123, 72 |
| 43, 547, 41, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 43 x 547 x 41 x 24 = 416603952
Therefore, the lowest common multiple of 774,547,738,432 is 416603952.
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 547 x 738 x 432 = 134979680448
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
547 : 1, 547
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,547,738,432, is 1.
Now, the common factors can be found like this.
774:2x 3x 3x 43
547:547
738:2x 3x 3x 41
432:2x 2x 2x 2x 3x 3x 3
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 3 = 324
Therefore, the value for common factors is 324.
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 = 134979680448/(1x324)
LCM = 134979680448/324
LCM = 416603952
Thus, we can understand that the LCM of 774,547,738,432 is 416603952.
