Given numbers are 214,468,121,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 214,468,121,686 is 2078304228.
Find LCM of 214,468,121,686 with Prime Factorization
| 2 | 214, 468, 121, 686 |
| 107, 234, 121, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 107 x 234 x 121 x 343 = 2078304228
Therefore, the lowest common multiple of 214,468,121,686 is 2078304228.
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.
214 x 468 x 121 x 686 = 8313216912
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.
214 : 1, 2, 107, 214
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
121 : 1, 11, 121
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 214,468,121,686, is 1.
Now, the common factors can be found like this.
214:2x 107
468:2x 2x 3x 3x 13
121:11x 11
686:2x 7x 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 2 = 4
Therefore, the value for common factors is 4.
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 = 8313216912/(1x4)
LCM = 8313216912/4
LCM = 2078304228
Thus, we can understand that the LCM of 214,468,121,686 is 2078304228.
