Given numbers are 778,738,927,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,738,927,168 is 827944488.
Find LCM of 778,738,927,168 with Prime Factorization
| 2 | 778, 738, 927, 168 |
| 3 | 389, 369, 927, 84 |
| 3 | 389, 123, 309, 28 |
| 389, 41, 103, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 389 x 41 x 103 x 28 = 827944488
Therefore, the lowest common multiple of 778,738,927,168 is 827944488.
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 738 x 927 x 168 = 89418004704
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
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
927 : 1, 3, 9, 103, 309, 927
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,738,927,168, is 1.
Now, the common factors can be found like this.
778:2x 389
738:2x 3x 3x 41
927:3x 3x 103
168:2x 2x 2x 3x 7
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 3 = 108
Therefore, the value for common factors is 108.
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 = 89418004704/(1x108)
LCM = 89418004704/108
LCM = 827944488
Thus, we can understand that the LCM of 778,738,927,168 is 827944488.
