Find LCM of 855,143,871,972,702 with Prime Factorization
| 2 | 855, 143, 871, 972, 702 |
| 3 | 855, 143, 871, 486, 351 |
| 3 | 285, 143, 871, 162, 117 |
| 3 | 95, 143, 871, 54, 39 |
| 13 | 95, 143, 871, 18, 13 |
| 95, 11, 67, 18, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 13 x 95 x 11 x 67 x 18 x 1 = 884709540
Therefore, the lowest common multiple of 855,143,871,972,702 is 884709540.
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.
855 x 143 x 871 x 972 x 702 = 72664733358360
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
143 : 1, 11, 13, 143
871 : 1, 13, 67, 871
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,143,871,972,702, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
143:11x 13
871:13x 67
972:2x 2x 3x 3x 3x 3x 3
702:2x 3x 3x 3x 13
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 3x 3x 13x 13 = 82134
Therefore, the value for common factors is 82134.
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 = 72664733358360/(1x82134)
LCM = 72664733358360/82134
LCM = 884709540
Thus, we can understand that the LCM of 855,143,871,972,702 is 884709540.
