Given numbers are 986,978,643,198
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 986,978,643,198 is 10230825726.
Find LCM of 986,978,643,198 with Prime Factorization
| 2 | 986, 978, 643, 198 |
| 3 | 493, 489, 643, 99 |
| 493, 163, 643, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 493 x 163 x 643 x 33 = 10230825726
Therefore, the lowest common multiple of 986,978,643,198 is 10230825726.
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.
986 x 978 x 643 x 198 = 122769908712
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
978 : 1, 2, 3, 6, 163, 326, 489, 978
643 : 1, 643
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 986,978,643,198, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
978:2x 3x 163
643:643
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 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 122769908712/(1x12)
LCM = 122769908712/12
LCM = 10230825726
Thus, we can understand that the LCM of 986,978,643,198 is 10230825726.
