Given numbers are 778,738,681,104,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,738,681,104,978 is 552360696264.
Find LCM of 778,738,681,104,978 with Prime Factorization
| 2 | 778, 738, 681, 104, 978 |
| 3 | 389, 369, 681, 52, 489 |
| 389, 123, 227, 52, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 389 x 123 x 227 x 52 x 163 = 552360696264
Therefore, the lowest common multiple of 778,738,681,104,978 is 552360696264.
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 681 x 104 x 978 = 39769970131008
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
681 : 1, 3, 227, 681
104 : 1, 2, 4, 8, 13, 26, 52, 104
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,738,681,104,978, is 1.
Now, the common factors can be found like this.
778:2x 389
738:2x 3x 3x 41
681:3x 227
104:2x 2x 2x 13
978:2x 3x 163
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 39769970131008/(1x72)
LCM = 39769970131008/72
LCM = 552360696264
Thus, we can understand that the LCM of 778,738,681,104,978 is 552360696264.
