The LCM of 187,685,864,680 is 110674080.
Find LCM of 187,685,864,680 with Prime Factorization
| 2 | 187, 685, 864, 680 |
| 2 | 187, 685, 432, 340 |
| 2 | 187, 685, 216, 170 |
| 5 | 187, 685, 108, 85 |
| 17 | 187, 137, 108, 17 |
| 11, 137, 108, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 11 x 137 x 108 x 1 = 110674080
Therefore, the lowest common multiple of 187,685,864,680 is 110674080.
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.
187 x 685 x 864 x 680 = 75258374400
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.
187 : 1, 11, 17, 187
685 : 1, 5, 137, 685
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,685,864,680, is 1.
Now, the common factors can be found like this.
187:11x 17
685:5x 137
864:2x 2x 2x 2x 2x 3x 3x 3
680:2x 2x 2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 17 = 680
Therefore, the value for common factors is 680.
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 = 75258374400/(1x680)
LCM = 75258374400/680
LCM = 110674080
Thus, we can understand that the LCM of 187,685,864,680 is 110674080.
