Given numbers are 785,701,681,717
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,701,681,717 is 89563836315.
Find LCM of 785,701,681,717 with Prime Factorization
| 3 | 785, 701, 681, 717 |
| 785, 701, 227, 239 |
Multiply the prime numbers at the bottom and the left side.
3 x 785 x 701 x 227 x 239 = 89563836315
Therefore, the lowest common multiple of 785,701,681,717 is 89563836315.
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.
785 x 701 x 681 x 717 = 268691508945
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.
785 : 1, 5, 157, 785
701 : 1, 701
681 : 1, 3, 227, 681
717 : 1, 3, 239, 717
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,701,681,717, is 1.
Now, the common factors can be found like this.
785:5x 157
701:701
681:3x 227
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.
3 = 3
Therefore, the value for common factors is 3.
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 = 268691508945/(1x3)
LCM = 268691508945/3
LCM = 89563836315
Thus, we can understand that the LCM of 785,701,681,717 is 89563836315.
