Given numbers are 121,806,465,196,213
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 121,806,465,196,213 is 10178788620.
Find LCM of 121,806,465,196,213 with Prime Factorization
| 2 | 121, 806, 465, 196, 213 |
| 3 | 121, 403, 465, 98, 213 |
| 31 | 121, 403, 155, 98, 71 |
| 121, 13, 5, 98, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 121 x 13 x 5 x 98 x 71 = 10178788620
Therefore, the lowest common multiple of 121,806,465,196,213 is 10178788620.
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.
121 x 806 x 465 x 196 x 213 = 1893254683320
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.
121 : 1, 11, 121
806 : 1, 2, 13, 26, 31, 62, 403, 806
465 : 1, 3, 5, 15, 31, 93, 155, 465
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
213 : 1, 3, 71, 213
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,806,465,196,213, is 1.
Now, the common factors can be found like this.
121:11x 11
806:2x 13x 31
465:3x 5x 31
196:2x 2x 7x 7
213:3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 31 = 186
Therefore, the value for common factors is 186.
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 = 1893254683320/(1x186)
LCM = 1893254683320/186
LCM = 10178788620
Thus, we can understand that the LCM of 121,806,465,196,213 is 10178788620.
