Given numbers are 249,422,966,458,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,422,966,458,221 is 856180692822.
Find LCM of 249,422,966,458,221 with Prime Factorization
| 2 | 249, 422, 966, 458, 221 |
| 3 | 249, 211, 483, 229, 221 |
| 83, 211, 161, 229, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 83 x 211 x 161 x 229 x 221 = 856180692822
Therefore, the lowest common multiple of 249,422,966,458,221 is 856180692822.
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.
249 x 422 x 966 x 458 x 221 = 10274168313864
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.
249 : 1, 3, 83, 249
422 : 1, 2, 211, 422
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
458 : 1, 2, 229, 458
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,422,966,458,221, is 1.
Now, the common factors can be found like this.
249:3x 83
422:2x 211
966:2x 3x 7x 23
458:2x 229
221:13x 17
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 3 = 12
Therefore, the value for common factors is 12.
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 = 10274168313864/(1x12)
LCM = 10274168313864/12
LCM = 856180692822
Thus, we can understand that the LCM of 249,422,966,458,221 is 856180692822.
