Given numbers are 717,442,989,717
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,442,989,717 is 313427946.
Find LCM of 717,442,989,717 with Prime Factorization
| 3 | 717, 442, 989, 717 |
| 239 | 239, 442, 989, 239 |
| 1, 442, 989, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 239 x 1 x 442 x 989 x 1 = 313427946
Therefore, the lowest common multiple of 717,442,989,717 is 313427946.
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.
717 x 442 x 989 x 717 = 224727837282
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.
717 : 1, 3, 239, 717
442 : 1, 2, 13, 17, 26, 34, 221, 442
989 : 1, 23, 43, 989
717 : 1, 3, 239, 717
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,442,989,717, is 1.
Now, the common factors can be found like this.
717:3x 239
442:2x 13x 17
989:23x 43
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.
3x 239 = 717
Therefore, the value for common factors is 717.
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 = 224727837282/(1x717)
LCM = 224727837282/717
LCM = 313427946
Thus, we can understand that the LCM of 717,442,989,717 is 313427946.
