Given numbers are 785,810,170,538,862
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,810,170,538,862 is 250647364710.
Find LCM of 785,810,170,538,862 with Prime Factorization
| 2 | 785, 810, 170, 538, 862 |
| 5 | 785, 405, 85, 269, 431 |
| 157, 81, 17, 269, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 157 x 81 x 17 x 269 x 431 = 250647364710
Therefore, the lowest common multiple of 785,810,170,538,862 is 250647364710.
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 810 x 170 x 538 x 862 = 50129472942000
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
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
170 : 1, 2, 5, 10, 17, 34, 85, 170
538 : 1, 2, 269, 538
862 : 1, 2, 431, 862
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,810,170,538,862, is 1.
Now, the common factors can be found like this.
785:5x 157
810:2x 3x 3x 3x 3x 5
170:2x 5x 17
538:2x 269
862:2x 431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 50129472942000/(1x200)
LCM = 50129472942000/200
LCM = 250647364710
Thus, we can understand that the LCM of 785,810,170,538,862 is 250647364710.
