Given numbers are 778,951,978,873
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,951,978,873 is 35094633174.
Find LCM of 778,951,978,873 with Prime Factorization
| 2 | 778, 951, 978, 873 |
| 3 | 389, 951, 489, 873 |
| 389, 317, 163, 291 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 389 x 317 x 163 x 291 = 35094633174
Therefore, the lowest common multiple of 778,951,978,873 is 35094633174.
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.
778 x 951 x 978 x 873 = 631703397132
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.
778 : 1, 2, 389, 778
951 : 1, 3, 317, 951
978 : 1, 2, 3, 6, 163, 326, 489, 978
873 : 1, 3, 9, 97, 291, 873
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,951,978,873, is 1.
Now, the common factors can be found like this.
778:2x 389
951:3x 317
978:2x 3x 163
873:3x 3x 97
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 3 = 18
Therefore, the value for common factors is 18.
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 = 631703397132/(1x18)
LCM = 631703397132/18
LCM = 35094633174
Thus, we can understand that the LCM of 778,951,978,873 is 35094633174.
