Given numbers are 673,649,441,702
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 673,649,441,702 is 15024255246.
Find LCM of 673,649,441,702 with Prime Factorization
| 3 | 673, 649, 441, 702 |
| 3 | 673, 649, 147, 234 |
| 673, 649, 49, 78 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 673 x 649 x 49 x 78 = 15024255246
Therefore, the lowest common multiple of 673,649,441,702 is 15024255246.
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.
673 x 649 x 441 x 702 = 135218297214
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.
673 : 1, 673
649 : 1, 11, 59, 649
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 673,649,441,702, is 1.
Now, the common factors can be found like this.
673:673
649:11x 59
441:3x 3x 7x 7
702:2x 3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 135218297214/(1x9)
LCM = 135218297214/9
LCM = 15024255246
Thus, we can understand that the LCM of 673,649,441,702 is 15024255246.
