Given numbers are 810,120,665,372,417
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,120,665,372,417 is 1856834280.
Find LCM of 810,120,665,372,417 with Prime Factorization
| 2 | 810, 120, 665, 372, 417 |
| 2 | 405, 60, 665, 186, 417 |
| 3 | 405, 30, 665, 93, 417 |
| 5 | 135, 10, 665, 31, 139 |
| 27, 2, 133, 31, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 27 x 2 x 133 x 31 x 139 = 1856834280
Therefore, the lowest common multiple of 810,120,665,372,417 is 1856834280.
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.
810 x 120 x 665 x 372 x 417 = 10026905112000
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
665 : 1, 5, 7, 19, 35, 95, 133, 665
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
417 : 1, 3, 139, 417
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,120,665,372,417, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
120:2x 2x 2x 3x 5
665:5x 7x 19
372:2x 2x 3x 31
417:3x 139
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 3x 3x 3x 5x 5 = 5400
Therefore, the value for common factors is 5400.
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 = 10026905112000/(1x5400)
LCM = 10026905112000/5400
LCM = 1856834280
Thus, we can understand that the LCM of 810,120,665,372,417 is 1856834280.
