Find LCM of 986,198,985,221,657 with Prime Factorization
| 2 | 986, 198, 985, 221, 657 |
| 3 | 493, 99, 985, 221, 657 |
| 3 | 493, 33, 985, 221, 219 |
| 17 | 493, 11, 985, 221, 73 |
| 29, 11, 985, 13, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 29 x 11 x 985 x 13 x 73 = 91246150710
Therefore, the lowest common multiple of 986,198,985,221,657 is 91246150710.
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.
986 x 198 x 985 x 221 x 657 = 27921322117260
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
985 : 1, 5, 197, 985
221 : 1, 13, 17, 221
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,198,985,221,657, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
198:2x 3x 3x 11
985:5x 197
221:13x 17
657:3x 3x 73
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 17 = 306
Therefore, the value for common factors is 306.
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 = 27921322117260/(1x306)
LCM = 27921322117260/306
LCM = 91246150710
Thus, we can understand that the LCM of 986,198,985,221,657 is 91246150710.
