The LCM of 978,418,511,978,754 is 39377432094.
Find LCM of 978,418,511,978,754 with Prime Factorization
2 | 978, 418, 511, 978, 754 |
3 | 489, 209, 511, 489, 377 |
163 | 163, 209, 511, 163, 377 |
1, 209, 511, 1, 377 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 1 x 209 x 511 x 1 x 377 = 39377432094
Therefore, the lowest common multiple of 978,418,511,978,754 is 39377432094.
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 418 x 511 x 978 x 754 = 154044514351728
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
418 : 1, 2, 11, 19, 22, 38, 209, 418
511 : 1, 7, 73, 511
978 : 1, 2, 3, 6, 163, 326, 489, 978
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,418,511,978,754, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
418:2x 11x 19
511:7x 73
978:2x 3x 163
754:2x 13x 29
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 2x 3x 163 = 3912
Therefore, the value for common factors is 3912.
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 = 154044514351728/(1x3912)
LCM = 154044514351728/3912
LCM = 39377432094
Thus, we can understand that the LCM of 978,418,511,978,754 is 39377432094.
