Find LCM of 685,668,286,975,187 with Prime Factorization
| 2 | 685, 668, 286, 975, 187 |
| 5 | 685, 334, 143, 975, 187 |
| 11 | 137, 334, 143, 195, 187 |
| 13 | 137, 334, 13, 195, 17 |
| 137, 334, 1, 15, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 13 x 137 x 334 x 1 x 15 x 17 = 16685654700
Therefore, the lowest common multiple of 685,668,286,975,187 is 16685654700.
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.
685 x 668 x 286 x 975 x 187 = 23860486221000
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.
685 : 1, 5, 137, 685
668 : 1, 2, 4, 167, 334, 668
286 : 1, 2, 11, 13, 22, 26, 143, 286
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,668,286,975,187, is 1.
Now, the common factors can be found like this.
685:5x 137
668:2x 2x 167
286:2x 11x 13
975:3x 5x 5x 13
187:11x 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 5x 11x 13 = 1430
Therefore, the value for common factors is 1430.
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 = 23860486221000/(1x1430)
LCM = 23860486221000/1430
LCM = 16685654700
Thus, we can understand that the LCM of 685,668,286,975,187 is 16685654700.
