Given numbers are 920,849,381,932
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,849,381,932 is 23112938280.
Find LCM of 920,849,381,932 with Prime Factorization
| 2 | 920, 849, 381, 932 |
| 2 | 460, 849, 381, 466 |
| 3 | 230, 849, 381, 233 |
| 230, 283, 127, 233 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 230 x 283 x 127 x 233 = 23112938280
Therefore, the lowest common multiple of 920,849,381,932 is 23112938280.
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.
920 x 849 x 381 x 932 = 277355259360
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
849 : 1, 3, 283, 849
381 : 1, 3, 127, 381
932 : 1, 2, 4, 233, 466, 932
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,849,381,932, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
849:3x 283
381:3x 127
932:2x 2x 233
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 3 = 12
Therefore, the value for common factors is 12.
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 = 277355259360/(1x12)
LCM = 277355259360/12
LCM = 23112938280
Thus, we can understand that the LCM of 920,849,381,932 is 23112938280.
