Given numbers are 693,638,603,486
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 693,638,603,486 is 72710946.
Find LCM of 693,638,603,486 with Prime Factorization
| 2 | 693, 638, 603, 486 |
| 3 | 693, 319, 603, 243 |
| 3 | 231, 319, 201, 81 |
| 11 | 77, 319, 67, 27 |
| 7, 29, 67, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 7 x 29 x 67 x 27 = 72710946
Therefore, the lowest common multiple of 693,638,603,486 is 72710946.
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.
693 x 638 x 603 x 486 = 129570905772
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
638 : 1, 2, 11, 22, 29, 58, 319, 638
603 : 1, 3, 9, 67, 201, 603
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,638,603,486, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
638:2x 11x 29
603:3x 3x 67
486:2x 3x 3x 3x 3x 3
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 3x 11 = 1782
Therefore, the value for common factors is 1782.
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 = 129570905772/(1x1782)
LCM = 129570905772/1782
LCM = 72710946
Thus, we can understand that the LCM of 693,638,603,486 is 72710946.
