Given numbers are 610,985,520,140,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 610,985,520,140,405 is 3543092280.
Find LCM of 610,985,520,140,405 with Prime Factorization
| 2 | 610, 985, 520, 140, 405 |
| 2 | 305, 985, 260, 70, 405 |
| 5 | 305, 985, 130, 35, 405 |
| 61, 197, 26, 7, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 61 x 197 x 26 x 7 x 81 = 3543092280
Therefore, the lowest common multiple of 610,985,520,140,405 is 3543092280.
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.
610 x 985 x 520 x 140 x 405 = 17715461400000
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.
610 : 1, 2, 5, 10, 61, 122, 305, 610
985 : 1, 5, 197, 985
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 610,985,520,140,405, is 5.
Now, the common factors can be found like this.
610:2x 5x 61
985:5x 197
520:2x 2x 2x 5x 13
140:2x 2x 5x 7
405:3x 3x 3x 3x 5
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 5x 5 = 1000
Therefore, the value for common factors is 1000.
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 = 17715461400000/(5x1000)
LCM = 17715461400000/5000
LCM = 3543092280
Thus, we can understand that the LCM of 610,985,520,140,405 is 3543092280.
