Given numbers are 235,705,580,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 235,705,580,978 is 13330140.
Find LCM of 235,705,580,978 with Prime Factorization
| 2 | 235, 705, 580, 978 |
| 3 | 235, 705, 290, 489 |
| 5 | 235, 235, 290, 163 |
| 47 | 47, 47, 58, 163 |
| 1, 1, 58, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 47 x 1 x 1 x 58 x 163 = 13330140
Therefore, the lowest common multiple of 235,705,580,978 is 13330140.
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.
235 x 705 x 580 x 978 = 93977487000
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.
235 : 1, 5, 47, 235
705 : 1, 3, 5, 15, 47, 141, 235, 705
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 235,705,580,978, is 1.
Now, the common factors can be found like this.
235:5x 47
705:3x 5x 47
580:2x 2x 5x 29
978:2x 3x 163
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 5x 5x 47 = 7050
Therefore, the value for common factors is 7050.
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 = 93977487000/(1x7050)
LCM = 93977487000/7050
LCM = 13330140
Thus, we can understand that the LCM of 235,705,580,978 is 13330140.
