Find LCM of 209,874,138,895,855 with Prime Factorization
| 2 | 209, 874, 138, 895, 855 |
| 3 | 209, 437, 69, 895, 855 |
| 5 | 209, 437, 23, 895, 285 |
| 19 | 209, 437, 23, 179, 57 |
| 23 | 11, 23, 23, 179, 3 |
| 11, 1, 1, 179, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 23 x 11 x 1 x 1 x 179 x 3 = 77440770
Therefore, the lowest common multiple of 209,874,138,895,855 is 77440770.
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 874 x 138 x 895 x 855 = 19289721399300
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
874 : 1, 2, 19, 23, 38, 46, 437, 874
138 : 1, 2, 3, 6, 23, 46, 69, 138
895 : 1, 5, 179, 895
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,874,138,895,855, is 1.
Now, the common factors can be found like this.
209:11x 19
874:2x 19x 23
138:2x 3x 23
895:5x 179
855:3x 3x 5x 19
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 5x 19x 19x 23 = 249090
Therefore, the value for common factors is 249090.
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 = 19289721399300/(1x249090)
LCM = 19289721399300/249090
LCM = 77440770
Thus, we can understand that the LCM of 209,874,138,895,855 is 77440770.
