Given numbers are 805,385,270,734,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,385,270,734,490 is 1228418730.
Find LCM of 805,385,270,734,490 with Prime Factorization
| 2 | 805, 385, 270, 734, 490 |
| 5 | 805, 385, 135, 367, 245 |
| 7 | 161, 77, 27, 367, 49 |
| 23, 11, 27, 367, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 23 x 11 x 27 x 367 x 7 = 1228418730
Therefore, the lowest common multiple of 805,385,270,734,490 is 1228418730.
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.
805 x 385 x 270 x 734 x 490 = 30096258885000
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
385 : 1, 5, 7, 11, 35, 55, 77, 385
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
734 : 1, 2, 367, 734
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,385,270,734,490, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
385:5x 7x 11
270:2x 3x 3x 3x 5
734:2x 367
490:2x 5x 7x 7
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 7x 7 = 24500
Therefore, the value for common factors is 24500.
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 = 30096258885000/(1x24500)
LCM = 30096258885000/24500
LCM = 1228418730
Thus, we can understand that the LCM of 805,385,270,734,490 is 1228418730.
