Given numbers are 987,598,978,591
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,598,978,591 is 18952747086.
Find LCM of 987,598,978,591 with Prime Factorization
| 2 | 987, 598, 978, 591 |
| 3 | 987, 299, 489, 591 |
| 329, 299, 163, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 329 x 299 x 163 x 197 = 18952747086
Therefore, the lowest common multiple of 987,598,978,591 is 18952747086.
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.
987 x 598 x 978 x 591 = 341149447548
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
598 : 1, 2, 13, 23, 26, 46, 299, 598
978 : 1, 2, 3, 6, 163, 326, 489, 978
591 : 1, 3, 197, 591
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,598,978,591, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
598:2x 13x 23
978:2x 3x 163
591:3x 197
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 3 = 18
Therefore, the value for common factors is 18.
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 = 341149447548/(1x18)
LCM = 341149447548/18
LCM = 18952747086
Thus, we can understand that the LCM of 987,598,978,591 is 18952747086.
