Given numbers are 764,774,638,411,509
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 764,774,638,411,509 is 6577083509436.
Find LCM of 764,774,638,411,509 with Prime Factorization
| 2 | 764, 774, 638, 411, 509 |
| 3 | 382, 387, 319, 411, 509 |
| 382, 129, 319, 137, 509 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 382 x 129 x 319 x 137 x 509 = 6577083509436
Therefore, the lowest common multiple of 764,774,638,411,509 is 6577083509436.
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.
764 x 774 x 638 x 411 x 509 = 78925002113232
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.
764 : 1, 2, 4, 191, 382, 764
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
638 : 1, 2, 11, 22, 29, 58, 319, 638
411 : 1, 3, 137, 411
509 : 1, 509
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,774,638,411,509, is 1.
Now, the common factors can be found like this.
764:2x 2x 191
774:2x 3x 3x 43
638:2x 11x 29
411:3x 137
509:509
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 3 = 12
Therefore, the value for common factors is 12.
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 = 78925002113232/(1x12)
LCM = 78925002113232/12
LCM = 6577083509436
Thus, we can understand that the LCM of 764,774,638,411,509 is 6577083509436.
