Find LCM of 978,918,819,315,265 with Prime Factorization
| 2 | 978, 918, 819, 315, 265 |
| 3 | 489, 459, 819, 315, 265 |
| 3 | 163, 153, 273, 105, 265 |
| 5 | 163, 51, 91, 35, 265 |
| 7 | 163, 51, 91, 7, 53 |
| 163, 51, 13, 1, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 163 x 51 x 13 x 1 x 53 = 3608423910
Therefore, the lowest common multiple of 978,918,819,315,265 is 3608423910.
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 918 x 819 x 315 x 265 = 61379290709100
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
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
265 : 1, 5, 53, 265
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,918,819,315,265, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
918:2x 3x 3x 3x 17
819:3x 3x 7x 13
315:3x 3x 5x 7
265:5x 53
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 3x 3x 3x 3x 5x 7 = 17010
Therefore, the value for common factors is 17010.
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 = 61379290709100/(1x17010)
LCM = 61379290709100/17010
LCM = 3608423910
Thus, we can understand that the LCM of 978,918,819,315,265 is 3608423910.
