Given numbers are 789,198,752,398,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,198,752,398,782 is 1523486525616.
Find LCM of 789,198,752,398,782 with Prime Factorization
| 2 | 789, 198, 752, 398, 782 |
| 3 | 789, 99, 376, 199, 391 |
| 263, 33, 376, 199, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 263 x 33 x 376 x 199 x 391 = 1523486525616
Therefore, the lowest common multiple of 789,198,752,398,782 is 1523486525616.
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.
789 x 198 x 752 x 398 x 782 = 36563676614784
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.
789 : 1, 3, 263, 789
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
398 : 1, 2, 199, 398
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,198,752,398,782, is 1.
Now, the common factors can be found like this.
789:3x 263
198:2x 3x 3x 11
752:2x 2x 2x 2x 47
398:2x 199
782:2x 17x 23
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 3 = 24
Therefore, the value for common factors is 24.
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 = 36563676614784/(1x24)
LCM = 36563676614784/24
LCM = 1523486525616
Thus, we can understand that the LCM of 789,198,752,398,782 is 1523486525616.
