Given numbers are 804,389,427,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 804,389,427,434 is 4139951172.
Find LCM of 804,389,427,434 with Prime Factorization
| 2 | 804, 389, 427, 434 |
| 7 | 402, 389, 427, 217 |
| 402, 389, 61, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 402 x 389 x 61 x 31 = 4139951172
Therefore, the lowest common multiple of 804,389,427,434 is 4139951172.
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.
804 x 389 x 427 x 434 = 57959316408
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
389 : 1, 389
427 : 1, 7, 61, 427
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,389,427,434, is 1.
Now, the common factors can be found like this.
804:2x 2x 3x 67
389:389
427:7x 61
434:2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 57959316408/(1x14)
LCM = 57959316408/14
LCM = 4139951172
Thus, we can understand that the LCM of 804,389,427,434 is 4139951172.
