Given numbers are 778,861,336,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,861,336,738 is 16076592.
Find LCM of 778,861,336,738 with Prime Factorization
| 2 | 778, 861, 336, 738 |
| 3 | 389, 861, 168, 369 |
| 7 | 389, 287, 56, 123 |
| 41 | 389, 41, 8, 123 |
| 389, 1, 8, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 389 x 1 x 8 x 3 = 16076592
Therefore, the lowest common multiple of 778,861,336,738 is 16076592.
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 861 x 336 x 738 = 166103348544
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
861 : 1, 3, 7, 21, 41, 123, 287, 861
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,861,336,738, is 1.
Now, the common factors can be found like this.
778:2x 389
861:3x 7x 41
336:2x 2x 2x 2x 3x 7
738:2x 3x 3x 41
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 7x 41 = 10332
Therefore, the value for common factors is 10332.
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 = 166103348544/(1x10332)
LCM = 166103348544/10332
LCM = 16076592
Thus, we can understand that the LCM of 778,861,336,738 is 16076592.
