Given numbers are 471,845,205,762,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 471,845,205,762,861 is 29013039510.
Find LCM of 471,845,205,762,861 with Prime Factorization
| 3 | 471, 845, 205, 762, 861 |
| 5 | 157, 845, 205, 254, 287 |
| 41 | 157, 169, 41, 254, 287 |
| 157, 169, 1, 254, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 41 x 157 x 169 x 1 x 254 x 7 = 29013039510
Therefore, the lowest common multiple of 471,845,205,762,861 is 29013039510.
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.
471 x 845 x 205 x 762 x 861 = 53529057895950
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.
471 : 1, 3, 157, 471
845 : 1, 5, 13, 65, 169, 845
205 : 1, 5, 41, 205
762 : 1, 2, 3, 6, 127, 254, 381, 762
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,845,205,762,861, is 1.
Now, the common factors can be found like this.
471:3x 157
845:5x 13x 13
205:5x 41
762:2x 3x 127
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 41 = 1845
Therefore, the value for common factors is 1845.
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 = 53529057895950/(1x1845)
LCM = 53529057895950/1845
LCM = 29013039510
Thus, we can understand that the LCM of 471,845,205,762,861 is 29013039510.
