Given numbers are 878,438,885,523
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 878,438,885,523 is 29666228370.
Find LCM of 878,438,885,523 with Prime Factorization
| 2 | 878, 438, 885, 523 |
| 3 | 439, 219, 885, 523 |
| 439, 73, 295, 523 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 439 x 73 x 295 x 523 = 29666228370
Therefore, the lowest common multiple of 878,438,885,523 is 29666228370.
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.
878 x 438 x 885 x 523 = 177997370220
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.
878 : 1, 2, 439, 878
438 : 1, 2, 3, 6, 73, 146, 219, 438
885 : 1, 3, 5, 15, 59, 177, 295, 885
523 : 1, 523
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,438,885,523, is 1.
Now, the common factors can be found like this.
878:2x 439
438:2x 3x 73
885:3x 5x 59
523:523
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 177997370220/(1x6)
LCM = 177997370220/6
LCM = 29666228370
Thus, we can understand that the LCM of 878,438,885,523 is 29666228370.
