Given numbers are 327,981,534,644,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 327,981,534,644,641 is 36041504436.
Find LCM of 327,981,534,644,641 with Prime Factorization
| 2 | 327, 981, 534, 644, 641 |
| 3 | 327, 981, 267, 322, 641 |
| 109 | 109, 327, 89, 322, 641 |
| 1, 3, 89, 322, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 109 x 1 x 3 x 89 x 322 x 641 = 36041504436
Therefore, the lowest common multiple of 327,981,534,644,641 is 36041504436.
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.
327 x 981 x 534 x 644 x 641 = 70713431703432
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.
327 : 1, 3, 109, 327
981 : 1, 3, 9, 109, 327, 981
534 : 1, 2, 3, 6, 89, 178, 267, 534
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 327,981,534,644,641, is 1.
Now, the common factors can be found like this.
327:3x 109
981:3x 3x 109
534:2x 3x 89
644:2x 2x 7x 23
641:641
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 3x 109 = 1962
Therefore, the value for common factors is 1962.
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 = 70713431703432/(1x1962)
LCM = 70713431703432/1962
LCM = 36041504436
Thus, we can understand that the LCM of 327,981,534,644,641 is 36041504436.
