Given numbers are 198,386,116,156,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,386,116,156,812 is 201693492.
Find LCM of 198,386,116,156,812 with Prime Factorization
| 2 | 198, 386, 116, 156, 812 |
| 2 | 99, 193, 58, 78, 406 |
| 3 | 99, 193, 29, 39, 203 |
| 29 | 33, 193, 29, 13, 203 |
| 33, 193, 1, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 29 x 33 x 193 x 1 x 13 x 7 = 201693492
Therefore, the lowest common multiple of 198,386,116,156,812 is 201693492.
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.
198 x 386 x 116 x 156 x 812 = 1123029363456
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
386 : 1, 2, 193, 386
116 : 1, 2, 4, 29, 58, 116
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,386,116,156,812, is 2.
Now, the common factors can be found like this.
198:2x 3x 3x 11
386:2x 193
116:2x 2x 29
156:2x 2x 3x 13
812:2x 2x 7x 29
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 2x 2x 3x 29 = 2784
Therefore, the value for common factors is 2784.
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 = 1123029363456/(2x2784)
LCM = 1123029363456/5568
LCM = 201693492
Thus, we can understand that the LCM of 198,386,116,156,812 is 201693492.
