The LCM of 963,868,686,531 is 2416540644.
Find LCM of 963,868,686,531 with Prime Factorization
| 2 | 963, 868, 686, 531 |
| 3 | 963, 434, 343, 531 |
| 3 | 321, 434, 343, 177 |
| 7 | 107, 434, 343, 59 |
| 107, 62, 49, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 107 x 62 x 49 x 59 = 2416540644
Therefore, the lowest common multiple of 963,868,686,531 is 2416540644.
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 868 x 686 x 531 = 304484121144
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
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
686 : 1, 2, 7, 14, 49, 98, 343, 686
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 963,868,686,531, is 1.
Now, the common factors can be found like this.
963:3x 3x 107
868:2x 2x 7x 31
686:2x 7x 7x 7
531:3x 3x 59
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 7 = 126
Therefore, the value for common factors is 126.
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 = 304484121144/(1x126)
LCM = 304484121144/126
LCM = 2416540644
Thus, we can understand that the LCM of 963,868,686,531 is 2416540644.
