Given numbers are 123,865,108,410,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,865,108,410,981 is 417493980.
Find LCM of 123,865,108,410,981 with Prime Factorization
| 2 | 123, 865, 108, 410, 981 |
| 3 | 123, 865, 54, 205, 981 |
| 3 | 41, 865, 18, 205, 327 |
| 5 | 41, 865, 6, 205, 109 |
| 41 | 41, 173, 6, 41, 109 |
| 1, 173, 6, 1, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 41 x 1 x 173 x 6 x 1 x 109 = 417493980
Therefore, the lowest common multiple of 123,865,108,410,981 is 417493980.
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.
123 x 865 x 108 x 410 x 981 = 4621658358600
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.
123 : 1, 3, 41, 123
865 : 1, 5, 173, 865
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
410 : 1, 2, 5, 10, 41, 82, 205, 410
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 123,865,108,410,981, is 1.
Now, the common factors can be found like this.
123:3x 41
865:5x 173
108:2x 2x 3x 3x 3
410:2x 5x 41
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.
2x 3x 3x 3x 5x 41 = 11070
Therefore, the value for common factors is 11070.
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 = 4621658358600/(1x11070)
LCM = 4621658358600/11070
LCM = 417493980
Thus, we can understand that the LCM of 123,865,108,410,981 is 417493980.
