Given numbers are 668,574,543,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,574,543,791 is 11763502044.
Find LCM of 668,574,543,791 with Prime Factorization
| 2 | 668, 574, 543, 791 |
| 7 | 334, 287, 543, 791 |
| 334, 41, 543, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 334 x 41 x 543 x 113 = 11763502044
Therefore, the lowest common multiple of 668,574,543,791 is 11763502044.
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.
668 x 574 x 543 x 791 = 164689028616
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.
668 : 1, 2, 4, 167, 334, 668
574 : 1, 2, 7, 14, 41, 82, 287, 574
543 : 1, 3, 181, 543
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,574,543,791, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
574:2x 7x 41
543:3x 181
791:7x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 164689028616/(1x14)
LCM = 164689028616/14
LCM = 11763502044
Thus, we can understand that the LCM of 668,574,543,791 is 11763502044.
