Given numbers are 845,507,401,832,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,507,401,832,981 is 21274044480.
Find LCM of 845,507,401,832,981 with Prime Factorization
| 3 | 845, 507, 401, 832, 981 |
| 13 | 845, 169, 401, 832, 327 |
| 13 | 65, 13, 401, 64, 327 |
| 5, 1, 401, 64, 327 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 13 x 5 x 1 x 401 x 64 x 327 = 21274044480
Therefore, the lowest common multiple of 845,507,401,832,981 is 21274044480.
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.
845 x 507 x 401 x 832 x 981 = 140217227167680
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.
845 : 1, 5, 13, 65, 169, 845
507 : 1, 3, 13, 39, 169, 507
401 : 1, 401
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,507,401,832,981, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
507:3x 13x 13
401:401
832:2x 2x 2x 2x 2x 2x 13
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 13x 13 = 6591
Therefore, the value for common factors is 6591.
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 = 140217227167680/(1x6591)
LCM = 140217227167680/6591
LCM = 21274044480
Thus, we can understand that the LCM of 845,507,401,832,981 is 21274044480.
