Given numbers are 861,482,738,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,482,738,403 is 501737418.
Find LCM of 861,482,738,403 with Prime Factorization
| 2 | 861, 482, 738, 403 |
| 3 | 861, 241, 369, 403 |
| 41 | 287, 241, 123, 403 |
| 7, 241, 3, 403 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 41 x 7 x 241 x 3 x 403 = 501737418
Therefore, the lowest common multiple of 861,482,738,403 is 501737418.
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.
861 x 482 x 738 x 403 = 123427404828
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
482 : 1, 2, 241, 482
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,482,738,403, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
482:2x 241
738:2x 3x 3x 41
403:13x 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 3x 41 = 246
Therefore, the value for common factors is 246.
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 = 123427404828/(1x246)
LCM = 123427404828/246
LCM = 501737418
Thus, we can understand that the LCM of 861,482,738,403 is 501737418.
