Given numbers are 978,642,371,489,269
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,642,371,489,269 is 10443566154.
Find LCM of 978,642,371,489,269 with Prime Factorization
| 2 | 978, 642, 371, 489, 269 |
| 3 | 489, 321, 371, 489, 269 |
| 163 | 163, 107, 371, 163, 269 |
| 1, 107, 371, 1, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 1 x 107 x 371 x 1 x 269 = 10443566154
Therefore, the lowest common multiple of 978,642,371,489,269 is 10443566154.
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.
978 x 642 x 371 x 489 x 269 = 30641423095836
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
642 : 1, 2, 3, 6, 107, 214, 321, 642
371 : 1, 7, 53, 371
489 : 1, 3, 163, 489
269 : 1, 269
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,642,371,489,269, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
642:2x 3x 107
371:7x 53
489:3x 163
269:269
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 163 = 2934
Therefore, the value for common factors is 2934.
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 = 30641423095836/(1x2934)
LCM = 30641423095836/2934
LCM = 10443566154
Thus, we can understand that the LCM of 978,642,371,489,269 is 10443566154.
