Given numbers are 760,891,978,589
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 760,891,978,589 is 3421689480.
Find LCM of 760,891,978,589 with Prime Factorization
| 2 | 760, 891, 978, 589 |
| 3 | 380, 891, 489, 589 |
| 19 | 380, 297, 163, 589 |
| 20, 297, 163, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 20 x 297 x 163 x 31 = 3421689480
Therefore, the lowest common multiple of 760,891,978,589 is 3421689480.
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.
760 x 891 x 978 x 589 = 390072600720
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.
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
978 : 1, 2, 3, 6, 163, 326, 489, 978
589 : 1, 19, 31, 589
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,891,978,589, is 1.
Now, the common factors can be found like this.
760:2x 2x 2x 5x 19
891:3x 3x 3x 3x 11
978:2x 3x 163
589:19x 31
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 19 = 114
Therefore, the value for common factors is 114.
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 = 390072600720/(1x114)
LCM = 390072600720/114
LCM = 3421689480
Thus, we can understand that the LCM of 760,891,978,589 is 3421689480.
