The LCM of 978,484,580,978,955 is 6554741820.
Find LCM of 978,484,580,978,955 with Prime Factorization
| 2 | 978, 484, 580, 978, 955 |
| 2 | 489, 242, 290, 489, 955 |
| 3 | 489, 121, 145, 489, 955 |
| 5 | 163, 121, 145, 163, 955 |
| 163 | 163, 121, 29, 163, 191 |
| 1, 121, 29, 1, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 163 x 1 x 121 x 29 x 1 x 191 = 6554741820
Therefore, the lowest common multiple of 978,484,580,978,955 is 6554741820.
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.
978 x 484 x 580 x 978 x 955 = 256421499998400
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
978 : 1, 2, 3, 6, 163, 326, 489, 978
955 : 1, 5, 191, 955
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,484,580,978,955, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
484:2x 2x 11x 11
580:2x 2x 5x 29
978:2x 3x 163
955:5x 191
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 2x 2x 3x 5x 163 = 39120
Therefore, the value for common factors is 39120.
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 = 256421499998400/(1x39120)
LCM = 256421499998400/39120
LCM = 6554741820
Thus, we can understand that the LCM of 978,484,580,978,955 is 6554741820.
