Given numbers are 963,817,825,645,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 963,817,825,645,663 is 47816007525.
Find LCM of 963,817,825,645,663 with Prime Factorization
| 3 | 963, 817, 825, 645, 663 |
| 5 | 321, 817, 275, 215, 221 |
| 43 | 321, 817, 55, 43, 221 |
| 321, 19, 55, 1, 221 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 43 x 321 x 19 x 55 x 1 x 221 = 47816007525
Therefore, the lowest common multiple of 963,817,825,645,663 is 47816007525.
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.
963 x 817 x 825 x 645 x 663 = 277571923682625
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.
963 : 1, 3, 9, 107, 321, 963
817 : 1, 19, 43, 817
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
645 : 1, 3, 5, 15, 43, 129, 215, 645
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 963,817,825,645,663, is 1.
Now, the common factors can be found like this.
963:3x 3x 107
817:19x 43
825:3x 5x 5x 11
645:3x 5x 43
663:3x 13x 17
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 5x 43 = 5805
Therefore, the value for common factors is 5805.
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 = 277571923682625/(1x5805)
LCM = 277571923682625/5805
LCM = 47816007525
Thus, we can understand that the LCM of 963,817,825,645,663 is 47816007525.
