Find LCM of 978,939,385,231,178 with Prime Factorization
| 2 | 978, 939, 385, 231, 178 |
| 3 | 489, 939, 385, 231, 89 |
| 7 | 163, 313, 385, 77, 89 |
| 11 | 163, 313, 55, 11, 89 |
| 163, 313, 5, 1, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 163 x 313 x 5 x 1 x 89 = 10488996210
Therefore, the lowest common multiple of 978,939,385,231,178 is 10488996210.
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 939 x 385 x 231 x 178 = 14537748747060
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
939 : 1, 3, 313, 939
385 : 1, 5, 7, 11, 35, 55, 77, 385
231 : 1, 3, 7, 11, 21, 33, 77, 231
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,939,385,231,178, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
939:3x 313
385:5x 7x 11
231:3x 7x 11
178:2x 89
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 7x 11 = 1386
Therefore, the value for common factors is 1386.
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 = 14537748747060/(1x1386)
LCM = 14537748747060/1386
LCM = 10488996210
Thus, we can understand that the LCM of 978,939,385,231,178 is 10488996210.
