The LCM of 187,680,680,209 is 142120.
Find LCM of 187,680,680,209 with Prime Factorization
2 | 187, 680, 680, 209 |
2 | 187, 340, 340, 209 |
2 | 187, 170, 170, 209 |
5 | 187, 85, 85, 209 |
11 | 187, 17, 17, 209 |
17 | 17, 17, 17, 19 |
1, 1, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 11 x 17 x 1 x 1 x 1 x 19 = 142120
Therefore, the lowest common multiple of 187,680,680,209 is 142120.
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 680 x 680 x 209 = 18071979200
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
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,680,680,209, is 1.
Now, the common factors can be found like this.
187:11x 17
680:2x 2x 2x 5x 17
680:2x 2x 2x 5x 17
209:11x 19
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 11x 17x 17 = 127160
Therefore, the value for common factors is 127160.
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 = 18071979200/(1x127160)
LCM = 18071979200/127160
LCM = 142120
Thus, we can understand that the LCM of 187,680,680,209 is 142120.
