The LCM of 189,879,638,660 is 353305260.
Find LCM of 189,879,638,660 with Prime Factorization
| 2 | 189, 879, 638, 660 |
| 3 | 189, 879, 319, 330 |
| 11 | 63, 293, 319, 110 |
| 63, 293, 29, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 63 x 293 x 29 x 10 = 353305260
Therefore, the lowest common multiple of 189,879,638,660 is 353305260.
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.
189 x 879 x 638 x 660 = 69954441480
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
879 : 1, 3, 293, 879
638 : 1, 2, 11, 22, 29, 58, 319, 638
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,879,638,660, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
879:3x 293
638:2x 11x 29
660:2x 2x 3x 5x 11
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 11 = 198
Therefore, the value for common factors is 198.
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 = 69954441480/(1x198)
LCM = 69954441480/198
LCM = 353305260
Thus, we can understand that the LCM of 189,879,638,660 is 353305260.
