The LCM of 680,175,843,616 is 220697400.
Find LCM of 680,175,843,616 with Prime Factorization
| 2 | 680, 175, 843, 616 |
| 2 | 340, 175, 843, 308 |
| 2 | 170, 175, 843, 154 |
| 5 | 85, 175, 843, 77 |
| 7 | 17, 35, 843, 77 |
| 17, 5, 843, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 17 x 5 x 843 x 11 = 220697400
Therefore, the lowest common multiple of 680,175,843,616 is 220697400.
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.
680 x 175 x 843 x 616 = 61795272000
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
175 : 1, 5, 7, 25, 35, 175
843 : 1, 3, 281, 843
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,175,843,616, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
175:5x 5x 7
843:3x 281
616:2x 2x 2x 7x 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 2x 2x 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 61795272000/(1x280)
LCM = 61795272000/280
LCM = 220697400
Thus, we can understand that the LCM of 680,175,843,616 is 220697400.
