Given numbers are 871,782,117,351
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 871,782,117,351 is 18390294.
Find LCM of 871,782,117,351 with Prime Factorization
| 3 | 871, 782, 117, 351 |
| 3 | 871, 782, 39, 117 |
| 13 | 871, 782, 13, 39 |
| 67, 782, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 67 x 782 x 1 x 3 = 18390294
Therefore, the lowest common multiple of 871,782,117,351 is 18390294.
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.
871 x 782 x 117 x 351 = 27971637174
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.
871 : 1, 13, 67, 871
782 : 1, 2, 17, 23, 34, 46, 391, 782
117 : 1, 3, 9, 13, 39, 117
351 : 1, 3, 9, 13, 27, 39, 117, 351
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,782,117,351, is 1.
Now, the common factors can be found like this.
871:13x 67
782:2x 17x 23
117:3x 3x 13
351:3x 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.
3x 3x 13x 13 = 1521
Therefore, the value for common factors is 1521.
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 = 27971637174/(1x1521)
LCM = 27971637174/1521
LCM = 18390294
Thus, we can understand that the LCM of 871,782,117,351 is 18390294.
