Given numbers are 179,878,749,351,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 179,878,749,351,921 is 12684543919866.
Find LCM of 179,878,749,351,921 with Prime Factorization
| 3 | 179, 878, 749, 351, 921 |
| 179, 878, 749, 117, 307 |
Multiply the prime numbers at the bottom and the left side.
3 x 179 x 878 x 749 x 117 x 307 = 12684543919866
Therefore, the lowest common multiple of 179,878,749,351,921 is 12684543919866.
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.
179 x 878 x 749 x 351 x 921 = 38053631759598
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.
179 : 1, 179
878 : 1, 2, 439, 878
749 : 1, 7, 107, 749
351 : 1, 3, 9, 13, 27, 39, 117, 351
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 179,878,749,351,921, is 1.
Now, the common factors can be found like this.
179:179
878:2x 439
749:7x 107
351:3x 3x 3x 13
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 38053631759598/(1x3)
LCM = 38053631759598/3
LCM = 12684543919866
Thus, we can understand that the LCM of 179,878,749,351,921 is 12684543919866.
