Given numbers are 844,672,431,560
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,672,431,560 is 305561760.
Find LCM of 844,672,431,560 with Prime Factorization
| 2 | 844, 672, 431, 560 |
| 2 | 422, 336, 431, 280 |
| 2 | 211, 168, 431, 140 |
| 2 | 211, 84, 431, 70 |
| 7 | 211, 42, 431, 35 |
| 211, 6, 431, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 211 x 6 x 431 x 5 = 305561760
Therefore, the lowest common multiple of 844,672,431,560 is 305561760.
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.
844 x 672 x 431 x 560 = 136891668480
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.
844 : 1, 2, 4, 211, 422, 844
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
431 : 1, 431
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,672,431,560, is 1.
Now, the common factors can be found like this.
844:2x 2x 211
672:2x 2x 2x 2x 2x 3x 7
431:431
560:2x 2x 2x 2x 5x 7
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 2x 2x 2x 7 = 448
Therefore, the value for common factors is 448.
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 = 136891668480/(1x448)
LCM = 136891668480/448
LCM = 305561760
Thus, we can understand that the LCM of 844,672,431,560 is 305561760.
