Given numbers are 215,835,340,242,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 215,835,340,242,648 is 47859067080.
Find LCM of 215,835,340,242,648 with Prime Factorization
| 2 | 215, 835, 340, 242, 648 |
| 2 | 215, 835, 170, 121, 324 |
| 5 | 215, 835, 85, 121, 162 |
| 43, 167, 17, 121, 162 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 167 x 17 x 121 x 162 = 47859067080
Therefore, the lowest common multiple of 215,835,340,242,648 is 47859067080.
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.
215 x 835 x 340 x 242 x 648 = 9571813416000
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.
215 : 1, 5, 43, 215
835 : 1, 5, 167, 835
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
242 : 1, 2, 11, 22, 121, 242
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,835,340,242,648, is 1.
Now, the common factors can be found like this.
215:5x 43
835:5x 167
340:2x 2x 5x 17
242:2x 11x 11
648:2x 2x 2x 3x 3x 3x 3
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 = 9571813416000/(1x200)
LCM = 9571813416000/200
LCM = 47859067080
Thus, we can understand that the LCM of 215,835,340,242,648 is 47859067080.
