Given numbers are 415,245,854,717
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 415,245,854,717 is 1778783790.
Find LCM of 415,245,854,717 with Prime Factorization
| 5 | 415, 245, 854, 717 |
| 7 | 83, 49, 854, 717 |
| 83, 7, 122, 717 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 83 x 7 x 122 x 717 = 1778783790
Therefore, the lowest common multiple of 415,245,854,717 is 1778783790.
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.
415 x 245 x 854 x 717 = 62257432650
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.
415 : 1, 5, 83, 415
245 : 1, 5, 7, 35, 49, 245
854 : 1, 2, 7, 14, 61, 122, 427, 854
717 : 1, 3, 239, 717
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 415,245,854,717, is 1.
Now, the common factors can be found like this.
415:5x 83
245:5x 7x 7
854:2x 7x 61
717:3x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 62257432650/(1x35)
LCM = 62257432650/35
LCM = 1778783790
Thus, we can understand that the LCM of 415,245,854,717 is 1778783790.
