Given numbers are 869,418,867,221,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,418,867,221,308 is 5210673468.
Find LCM of 869,418,867,221,308 with Prime Factorization
| 2 | 869, 418, 867, 221, 308 |
| 11 | 869, 209, 867, 221, 154 |
| 17 | 79, 19, 867, 221, 14 |
| 79, 19, 51, 13, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 79 x 19 x 51 x 13 x 14 = 5210673468
Therefore, the lowest common multiple of 869,418,867,221,308 is 5210673468.
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.
869 x 418 x 867 x 221 x 308 = 21436710647352
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.
869 : 1, 11, 79, 869
418 : 1, 2, 11, 19, 22, 38, 209, 418
867 : 1, 3, 17, 51, 289, 867
221 : 1, 13, 17, 221
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,418,867,221,308, is 1.
Now, the common factors can be found like this.
869:11x 79
418:2x 11x 19
867:3x 17x 17
221:13x 17
308:2x 2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 17 = 4114
Therefore, the value for common factors is 4114.
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 = 21436710647352/(1x4114)
LCM = 21436710647352/4114
LCM = 5210673468
Thus, we can understand that the LCM of 869,418,867,221,308 is 5210673468.
