Given numbers are 769,543,468,513,786
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 769,543,468,513,786 is 486403755084.
Find LCM of 769,543,468,513,786 with Prime Factorization
| 2 | 769, 543, 468, 513, 786 |
| 3 | 769, 543, 234, 513, 393 |
| 3 | 769, 181, 78, 171, 131 |
| 769, 181, 26, 57, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 769 x 181 x 26 x 57 x 131 = 486403755084
Therefore, the lowest common multiple of 769,543,468,513,786 is 486403755084.
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.
769 x 543 x 468 x 513 x 786 = 78797408323608
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.
769 : 1, 769
543 : 1, 3, 181, 543
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
513 : 1, 3, 9, 19, 27, 57, 171, 513
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,543,468,513,786, is 1.
Now, the common factors can be found like this.
769:769
543:3x 181
468:2x 2x 3x 3x 13
513:3x 3x 3x 19
786:2x 3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 78797408323608/(1x162)
LCM = 78797408323608/162
LCM = 486403755084
Thus, we can understand that the LCM of 769,543,468,513,786 is 486403755084.
