Find LCM of 657,987,686,593,198 with Prime Factorization
| 2 | 657, 987, 686, 593, 198 |
| 3 | 657, 987, 343, 593, 99 |
| 3 | 219, 329, 343, 593, 33 |
| 7 | 73, 329, 343, 593, 11 |
| 73, 47, 49, 593, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 73 x 47 x 49 x 593 x 11 = 138176669862
Therefore, the lowest common multiple of 657,987,686,593,198 is 138176669862.
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.
657 x 987 x 686 x 593 x 198 = 52230781207836
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.
657 : 1, 3, 9, 73, 219, 657
987 : 1, 3, 7, 21, 47, 141, 329, 987
686 : 1, 2, 7, 14, 49, 98, 343, 686
593 : 1, 593
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,987,686,593,198, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
987:3x 7x 47
686:2x 7x 7x 7
593:593
198:2x 3x 3x 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 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 52230781207836/(1x378)
LCM = 52230781207836/378
LCM = 138176669862
Thus, we can understand that the LCM of 657,987,686,593,198 is 138176669862.
