Given numbers are 691,657,468,459,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,657,468,459,803 is 13243708764.
Find LCM of 691,657,468,459,803 with Prime Factorization
| 3 | 691, 657, 468, 459, 803 |
| 3 | 691, 219, 156, 153, 803 |
| 73 | 691, 73, 52, 51, 803 |
| 691, 1, 52, 51, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 73 x 691 x 1 x 52 x 51 x 11 = 13243708764
Therefore, the lowest common multiple of 691,657,468,459,803 is 13243708764.
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.
691 x 657 x 468 x 459 x 803 = 78310049921532
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.
691 : 1, 691
657 : 1, 3, 9, 73, 219, 657
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
459 : 1, 3, 9, 17, 27, 51, 153, 459
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,657,468,459,803, is 1.
Now, the common factors can be found like this.
691:691
657:3x 3x 73
468:2x 2x 3x 3x 13
459:3x 3x 3x 17
803:11x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 73 = 5913
Therefore, the value for common factors is 5913.
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 = 78310049921532/(1x5913)
LCM = 78310049921532/5913
LCM = 13243708764
Thus, we can understand that the LCM of 691,657,468,459,803 is 13243708764.
