Given numbers are 927,189,643,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 927,189,643,634 is 7935956154.
Find LCM of 927,189,643,634 with Prime Factorization
| 3 | 927, 189, 643, 634 |
| 3 | 309, 63, 643, 634 |
| 103, 21, 643, 634 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 103 x 21 x 643 x 634 = 7935956154
Therefore, the lowest common multiple of 927,189,643,634 is 7935956154.
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.
927 x 189 x 643 x 634 = 71423605386
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.
927 : 1, 3, 9, 103, 309, 927
189 : 1, 3, 7, 9, 21, 27, 63, 189
643 : 1, 643
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 927,189,643,634, is 1.
Now, the common factors can be found like this.
927:3x 3x 103
189:3x 3x 3x 7
643:643
634:2x 317
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 = 71423605386/(1x9)
LCM = 71423605386/9
LCM = 7935956154
Thus, we can understand that the LCM of 927,189,643,634 is 7935956154.
