Given numbers are 865,529,655,720,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,529,655,720,489 is 1406997000720.
Find LCM of 865,529,655,720,489 with Prime Factorization
| 3 | 865, 529, 655, 720, 489 |
| 5 | 865, 529, 655, 240, 163 |
| 173, 529, 131, 48, 163 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 173 x 529 x 131 x 48 x 163 = 1406997000720
Therefore, the lowest common multiple of 865,529,655,720,489 is 1406997000720.
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.
865 x 529 x 655 x 720 x 489 = 105524775054000
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.
865 : 1, 5, 173, 865
529 : 1, 23, 529
655 : 1, 5, 131, 655
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,529,655,720,489, is 1.
Now, the common factors can be found like this.
865:5x 173
529:23x 23
655:5x 131
720:2x 2x 2x 2x 3x 3x 5
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5 = 75
Therefore, the value for common factors is 75.
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 = 105524775054000/(1x75)
LCM = 105524775054000/75
LCM = 1406997000720
Thus, we can understand that the LCM of 865,529,655,720,489 is 1406997000720.
