Find LCM of 685,690,863,371,180 with Prime Factorization
2 | 685, 690, 863, 371, 180 |
3 | 685, 345, 863, 371, 90 |
5 | 685, 115, 863, 371, 30 |
137, 23, 863, 371, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 137 x 23 x 863 x 371 x 6 = 181595722140
Therefore, the lowest common multiple of 685,690,863,371,180 is 181595722140.
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 690 x 863 x 371 x 180 = 27239358321000
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
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
863 : 1, 863
371 : 1, 7, 53, 371
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,690,863,371,180, is 1.
Now, the common factors can be found like this.
685:5x 137
690:2x 3x 5x 23
863:863
371:7x 53
180:2x 2x 3x 3x 5
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 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 27239358321000/(1x150)
LCM = 27239358321000/150
LCM = 181595722140
Thus, we can understand that the LCM of 685,690,863,371,180 is 181595722140.
