Find LCM of 209,378,297,962,856 with Prime Factorization
| 2 | 209, 378, 297, 962, 856 |
| 3 | 209, 189, 297, 481, 428 |
| 3 | 209, 63, 99, 481, 428 |
| 3 | 209, 21, 33, 481, 428 |
| 11 | 209, 7, 11, 481, 428 |
| 19, 7, 1, 481, 428 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 11 x 19 x 7 x 1 x 481 x 428 = 16263983736
Therefore, the lowest common multiple of 209,378,297,962,856 is 16263983736.
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.
209 x 378 x 297 x 962 x 856 = 19321612678368
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.
209 : 1, 11, 19, 209
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
297 : 1, 3, 9, 11, 27, 33, 99, 297
962 : 1, 2, 13, 26, 37, 74, 481, 962
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,378,297,962,856, is 1.
Now, the common factors can be found like this.
209:11x 19
378:2x 3x 3x 3x 7
297:3x 3x 3x 11
962:2x 13x 37
856:2x 2x 2x 107
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 3x 3x 3x 11 = 1188
Therefore, the value for common factors is 1188.
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 = 19321612678368/(1x1188)
LCM = 19321612678368/1188
LCM = 16263983736
Thus, we can understand that the LCM of 209,378,297,962,856 is 16263983736.
