Given numbers are 830,657,129,978,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 830,657,129,978,580 is 221680511820.
Find LCM of 830,657,129,978,580 with Prime Factorization
| 2 | 830, 657, 129, 978, 580 |
| 3 | 415, 657, 129, 489, 290 |
| 5 | 415, 219, 43, 163, 290 |
| 83, 219, 43, 163, 58 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 83 x 219 x 43 x 163 x 58 = 221680511820
Therefore, the lowest common multiple of 830,657,129,978,580 is 221680511820.
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.
830 x 657 x 129 x 978 x 580 = 39902492127600
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.
830 : 1, 2, 5, 10, 83, 166, 415, 830
657 : 1, 3, 9, 73, 219, 657
129 : 1, 3, 43, 129
978 : 1, 2, 3, 6, 163, 326, 489, 978
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,657,129,978,580, is 1.
Now, the common factors can be found like this.
830:2x 5x 83
657:3x 3x 73
129:3x 43
978:2x 3x 163
580:2x 2x 5x 29
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 39902492127600/(1x180)
LCM = 39902492127600/180
LCM = 221680511820
Thus, we can understand that the LCM of 830,657,129,978,580 is 221680511820.
