Given numbers are 978,533,557,198
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,533,557,198 is 9581537394.
Find LCM of 978,533,557,198 with Prime Factorization
| 2 | 978, 533, 557, 198 |
| 3 | 489, 533, 557, 99 |
| 163, 533, 557, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 533 x 557 x 33 = 9581537394
Therefore, the lowest common multiple of 978,533,557,198 is 9581537394.
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 533 x 557 x 198 = 57489224364
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
533 : 1, 13, 41, 533
557 : 1, 557
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,533,557,198, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
533:13x 41
557:557
198:2x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 57489224364/(1x6)
LCM = 57489224364/6
LCM = 9581537394
Thus, we can understand that the LCM of 978,533,557,198 is 9581537394.
