Given numbers are 605,900,644,275
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,900,644,275 is 17532900.
Find LCM of 605,900,644,275 with Prime Factorization
| 2 | 605, 900, 644, 275 |
| 2 | 605, 450, 322, 275 |
| 5 | 605, 225, 161, 275 |
| 5 | 121, 45, 161, 55 |
| 11 | 121, 9, 161, 11 |
| 1, 9, 161, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 11 x 1 x 9 x 161 x 11 = 17532900
Therefore, the lowest common multiple of 605,900,644,275 is 17532900.
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.
605 x 900 x 644 x 275 = 96430950000
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.
605 : 1, 5, 11, 55, 121, 605
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
275 : 1, 5, 11, 25, 55, 275
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,900,644,275, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
900:2x 2x 3x 3x 5x 5
644:2x 2x 7x 23
275:5x 5x 11
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 5x 5x 5x 11 = 5500
Therefore, the value for common factors is 5500.
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 = 96430950000/(1x5500)
LCM = 96430950000/5500
LCM = 17532900
Thus, we can understand that the LCM of 605,900,644,275 is 17532900.
